This is the first video that explained things without the presenter trying to explain every little thing in an attempt to prove how smart they are. This video may be a few years hold but I can easily see how each area is actually independent of others. Very useful indeed. Thank you for posting.
Thank you sir. Amazing how you care about the listener. It is all the more important when the latter is not a native english speaker but only a french peasant living close to La Rochelle. I started my layout 12 months ago, all DC, and you help me tremendously to get ready to shift soon to DCC when setting up my second layout (US shaped). Enjoyable to learn this way. Take care.
My Pacific Crest is my fifth over the last 47 years of layouts. Many components were saved from the first four to be used on this 5th one. Thanks for including solenoid switch motors as part of the discussion and describing them as "gun shots" in operation! Fear not, I have already converted to slow motion motors, but only for those points I cannot easy reach. Everything else will be ground throws due to my slim budget and my lack of computer knowledge. You won't see this old boy going to "Gold". Well done on this one, Sir. I have it bookmarked for further study!
Hi Randall, I’m so pleased that you enjoyed the video. Yes the slow action motors are so much better but the price is somewhat expensive. Regards Charlie
I am thinking of making a small DCC/PC controlled layout myself and this excellent film has helped me make up my mind to go ahead. As I already have the NCE Power Cab I will stick with their equipment but I will certainly try to use your extremely neat wiring style.. Thanks for posting such an informative video.

A very interesting video Charlie. I too use technology in my railway modelling. As a former electronics engineer I build my own control circuits many using Merg kits as the basis. My control system is the free JMRI software and this is connected to my NCE system via usb. I did look at the paid for software but decided that it was too expensive to risk finding a feature that I need is missing. With JMRI I can add capability using the many built in facilities, The down side is that there is a very steep learning curve to negociate before you get anything going. There is also a lot to be said for using parts from one manufacturer as you have and knowing they will all work together. ..............John
I too initially thought about JMRI but as you mentioned the learning curve is very steep. I must admit to my addiction to automation! It is very satisfying to overcome the software’s reluctance to give in straight away and win the small battles as the layout progresses.
Very informative, I'm looking at starting into the hobby and researching and learning as much as I can before I begin purchasing products. For sure I need more education before I start. Did enjoy your layout, very clean and apparently very functional. Great Job.

I'm aware this is an older video, but can I say, would it be possible to maybe make a small tail chaser to demonstrate how simple basic DCC wiring is? this massively overwhelmed me
Hello again, there is a simple thing i used to do to stop that loud noise from the solenoid point motors years ago, and thats to fit slim rubber O Rings the the part of the point that throws, this massively dampens the sound to the point the sound is halved
Same here m8, i have ocd about these things and will triple check everything lol! but yea im looking into full PC automation using N gauge, ive heard the bachmann dynamis ultima can do this?
Hello, Charlie. Very informative video. At the age of 73 I am about to build my first layout. Is it possible for a engine, not fitted with decoder, to run on a DCC track and, for a engine fitted with a decoder, to run on a none DCC track? Thank you. Kind regards, Tom.
Been subbed for ages on my own channel but just subbed on my railway channel. Working my way through the videos in no particular order. Really enjoy the way you film and it's good when you make mistakes and admit it then show how to sort the problems 👍🏻 Keep up the good work.
Good afternoon in regards to wiring do what guage do you use for all the different bits and bobs i.e power ect.When wiring a dcc chip to a loco what wiring would you use for that hope all is well Ken
Hi Ken it’s very difficult to suggest which cable sizes you should use, it’s all to do with how much power you intend to draw. I suggest you get in contact with James from DCC Train Automation. He will give you all the assistance you need. Regards Charlie
(Edited Update)... Wow, plenty of spaghetti there to feed you for a week if you could eat it, LOL. Tho with you upending the boards like this and have shown how you have kept it neat and tidy from one section to the next is impressive Charlie. Do you have OCD... LOL. No with my early days doing Electric Engineering and Electronics back in the mid-80s. Taught me how to control the flow of wiring to different sections and to have every aspect of it neat and tidy, especially for fault finding. At times it can look bewildering, but colour coding and labeling everything makes it a lot simpler to follow one end to the next. This is a must in the IT Depts (that I worked in the NHS) for servers etc as your not working between two baseboards next to each other, but from room to room, building to building. So a label like B2S15IO31PC101 would be Building #2 - Server #15 Input/output network socket 31 to the PC #121 (1st floor on computer 21). Long Labels they maybe but if you're at B10S09IO17PC523 you know where to go. Therefore logically baseboards can be the same B1PM05S09 (Baseboard #1 - Point Motor #05 - Signal #09) even to the extent that the label points out both ends of the cable going from and to elsewhere (as above) would be B1PM05S09 - CP01TB03SW19 (Control Panel #01, Terminal Block #03, Switch #19). Long-winded maybe, but useful in a wiring diagram in your layout folder that has six A4 pages for a 6x baseboard layout. Edit Update: Oops I forgot to say that the label L1 closest to the T1 terminated end is that location. The 2nd label L2 is then the T2 terminated end away from this point to its location. T1 12v @ ----- wire/cable ---- @ switch T2 etc, etc, etc I think I got that right... LOL, anyway, hopefully, that will help any beginners with their designs on paper to draw the layouts connection points of wiring and to label the physical wires on the baseboards. To make the labels: just cut an average address label into strips to suit your needs. Then wrap it around the wire as you would with a Loaf of Bread sticky Sealer tape and write the info on it. If printing the info on a sheet of A4 and cutting them out, but remember to leave the same length of blank space after your text and cut out. Add a few extra spaces (4mm) to cater to the thickness of the wire. Now place the cut-out strip of text paper and lay it flat on a clean area of your work table. Now get your roll-off Sellotape and pull a cut strip of it longer than your label, and place it lengthwise on top of your label, but centered the best you can top and bottom and stick it down gently on top. Next is to peel it up again with the text stuck to it and wrap it around your wire so that the sellotape sticks to its self (like the bread sealer). Lastly, cut away the excess clear sellotape leaving 1-2mm around the edges of your label to stop it from opening and falling off.
My notes are even larger than 6 pages. Each piece of electronics also has a page! Good notes are essential. I’ve learned the hard way. After a couple of weeks away, I returned to my model Railway club. I was shocked to find that one board had been wired completely with orange cable!
@@ChadwickModelRailway Yeah it is a matter of it being kept as a KISS (Keep It Simple Stupid) plan. Orange is a favourable colour over here in Belfast... LOL even LOL (Orange Lodge Halls IDs e.g. LOL45 etc). Funny thing if I built a prototypical layout of the NIR from the 70s in Summer. I would have to paint the house Gable Walls with Murals and the kerbstones in Red, White and Blue too, LMFAO.
Very impressive! I am planning to go DCC for the first time, although I have no desire to go full automation with computer control; too much of a "Luddite" for that!! Being able to control more than one loco' at a time, and the sound functions is what interests me, so we shall see how things progress from there. Another excellent video which has proved useful to me as I plan the layout....Cheers!!
The thing is though charlie, it really can be as simple as 2 wires going all the way up to hundreds of wires, One thing i cannot grasp is how they can charge £300 for TrainController software that's only a 16MB file! I know you only ever have to buy it once but damn man, are these people living 20 years in the future or something? I sat down last night with a calculator to add up how much everything i need would cost in N gauge, at the moment i'm up to £2,050 and counting! I'm going for the digikeijs dr5000 system, it does absolutely everything, Anyway charlie your videos are the best on youtube
Good luck with your automation and do keep this community posted with your progress. There is of course, JMRI which is free but apparently, it’s a little less user friendly. Regards Charlie
Hi Charlie, Great video, I use Railmaster and like you say one short and everything stops. I am a pensioner and on a budget, so I have to use what I can afford. thanks for sharing .......John.
Hey, I’m just starting my dcc layout and like the idea of having the separate power districts to prevent the whole layout shorting out if I have one. I was looking at those PM42’s and was wondering if they work with other brands/products. I want to keep things as simple as possible for now and I’ll be running from a hornby select controller to start with. In my mind I’d be putting the main power into the PM42 and running the BUS wires from them into the separate districts. Would this work 😅
The PM42 is ideal for Digitrax layouts. However, there are better solid state options that are cheaper. Give James a call at DCC TrainAutomation 01823 429309.
Excellent video, Charlie. As others have commented, neatly wired and strapped into harnesses, and that makes the wiring diagrams so much more important. Do you think there is a benefit to using different wiring colours, or do the diagrams look after all that for you? Diagrams detailed down to pin level for the controllers, and “pin level” at the solenoids and lights? An image or example of the level of detail you have found effective would be most helpful, please. As usual, clear and entertaining, so looking forward to the next one! Regards, Tom
Hi Charlie. Pined type Choklad block can i you give a link for these. i live in Denmark, we don´t that type ? love you Channel and are learning a lot about modeltrains. Thanks Flemming
Charlie , a question for you can you suggest a power unit for a dc layout spread over 2 x 8' x 4' boards , this will need to cover up and down line outer circle plus fiddle yard . I need to have constant voltage over all aspects , this layout will hopefully be updated to DCC late 2021 early 2022 . Hope you can help
Hi. So I'm about to (once the garage is cleared) embark on an insane project and having watched a lot of your stuff as well as others I am heading down the Digitrax route. I'm intending to use some computer control (currently JMRI most likely as I can run that on a Pi) but currently just planning stuff. However have hit on an issue that I just cant get my head around as I cant find the info: The numbering / Board IDs etc of all the devices. Going to have PM42s DBL168s DS64s (about 24 of the buggers so may need a new mortgage) and an SE8C. I *think* all the board ids can overlap between devices, so there can ba a 42 that is a 1, 168 that is a 1 etc. But, particularly with the block detection, switches and light outputs of the SE8C there seems to be some concern about overlap. Have you any idea what can overlap, what cant overlap, and any hints on numbering all these devices! Cheers and loving the channel!
Ian, you have no worries on this one as I'm sure that can have the same ID. When building this layout, I called the first board, Board 1. So the DS64 numbers are 101 and 102. The points also start with a 1. 11, 12, 13 etc. The BDL168 is 101 On Board 4 they are 401 and 402 etc. You just need a routine that works for you. When it comes to computer inputs it will ask for the DS64 number and its point numbers. Good luck, its a long journey!
Appreciate Video clip! Apologies for butting in, I would appreciate your initial thoughts. Have you ever tried - Januke Henatalie Formula (google it)? It is a great exclusive guide for operating a DCC model railroad minus the normal expense. Ive heard some interesting things about it and my work buddy at last got great results with it.
Great vid Charlie, think I'll have to stick to my old analogue gaugemasters- as my late Grandfather used to say "it's a bit too testicle for me" Regards Terry.
@@ChadwickModelRailway Hi Charlie I am running some railway beginners workshops in April in Denham west London would you be interested in running one on electrics? stephenbeamon@gmail.com Thanks
I would be interested to find out how often you set it up at an exhibition and have to do some form of troubleshooting to make it work properly vs how often you just set it up and enjoy? Cheers, Michael
Hi Michael, it ran pretty good to be honest. The only drawback was having the rails cross the board join at an angle. A schoolboy error really. Regards Charlie
So much about DCC confuses me. How are the seperate power districts seperated; is that simply with insulated rail joiners? And, where do boosters come into play?
Hi Gabe, I think that you are over complicating DCC. Boosters are only required on large layouts that need more power than your system can provide. Most controllers produced 5 amps and that is normally ample. Power districts are also not essential and need to be planned at the initial wiring stage. Insulated rail joiners are only normally used when electrofrog points are installed. The shop “Digitrains” can offer unbiased advice. Regards Charlie.
Hi Charlie. Just started out a simple layout with my son. Great videos with a lot of insight! I'm struggling at the moment with the wiring side of things though. Currently running DC. Can I connect 2 separate tracks together without any issues/ short circuits? Thanks in advance. Paul B.
Good day to you , Can you tell me what type of cables you used, feeders, points and block detector, in mms? I see you use Digitrax. Thanks and your videos are great help, keep them coming.
Very interesting, and a great video. I was wondering if you were able to do a video regarding block detection and signalling wiring? I.e. I'm always impressed when the trains are able to pull-up to a station or signal but not 100% on how and where to place the breaks or detection for circuit features
@@ChadwickModelRailway thank you for the reply i am thinking of probably going with half dc and half dcc so i can run both dcc and the older 1980s lima locos i have. thank you for the help.
Charlie, I have been greatly enjoying your videos this year. I am currently planning my first DCC layout. Whilst most of the subjects you cover I understand the electrics side of it I really don't understand. Can you recommend a book for a complete DCC wiring guide please, Thank you Stephen Allen
Thanks Stephen I’m so pleased you enjoyed the channel. I’m sorry I can’t recommend a D cc wiring book but I’m sure there must be some on the market. Take care regards Charlie
Just a question. I own HO scale trains. I've been going DC. Now, I'm considering DCC. Question: say I have 4 trains: the locomotive, freight, tanker and caboose. I realize that the locomotive MUST be DCC-ready but must the other three be DCC-ready? Sorry for the dumb question. Can anyone help?
Hi Obeeone, yes DCC is all or nothing. You need a DCC controller which will deliver 15v AC. DC layouts use 12v DC. Then you have to fit a DCC decoder into every loco. It’s a pricy conversion but could be worth it depending on your aspirations. Hopefully you have subscribed too.
Charlie. Any chance you can at some point do an idiot’s guide for those of us who feel we have made the mistake of opting for DC and realising we have rather opted for the Stone Age solution?
Hello, I wondered if you could give advise on equipment I need to run Traincontroller ( Silver) such as: Command station etc. I would have: 1. around 20-3O blocks 2. 30+ turnouts ( servo type ) 3. Signals 2 and 3 aspect not sure how many yet. Would be possible if I could contact you for more details.. Many thanks
Wow Alan, what a question! I use Digitrax but there are others such as Lenz and I think NCE can do it as well. The buget that you will require is not small. A Digitrax system cost around £350. To carry out block detection, a BDL168 detects 16 blocks and retails at £135. TC Silver costs around £350. I suggest you find Rudy, (rudysmodelrailway) on TH-cam. He has a great series of videos and explains in great detail, how TC works. You might also phone Digitrains and ask for their guidance and prices. Good luck. Regards Charlie
Super fantastic video! Very informative and it does give a good insight to how, if wanted, to advance your layout. A question if I may, as you said you are using a few Seep Solenoids, have you been able to get these to work with the DS64? I have struggled with this and so have others and I would very much appreciate any information or help on this matter. If you message me I am happy to provide my email for easier communication. Thank you! Des
Hi Des, I have had no problems at all with SEEPs. I only install them when the original Peco motor/switch became problematic. I imagine that you have electro frog points and have programmed your DS64 correctly. I can email you a photo of the wiring of the SEEPs and DS64, if you send me your email address. I can delete the email address once your message arrives. Regards Charlie
on my analogue Model Railway technically I can run 10 trains at one time , However they will derail and Crash . I can on my own run 3 trains safely with a 4 train shunting and running round etc.my question is if I convert my 250 powered 00 trains will DCC Stop them derailing . of course I would have to become a millionaire to convert.
I understand that it is 'possible' to control points at the controller, I just don't understand why anyone would do it. I am a member of a club which displays a simple exhibition layout. The 'expert' who set up the DCC insisted on controlling the points using the Digitrax handsets. He understands it, but he does not turn up to operate it at exhibitions. Everyone who does has to learn the controls and then operate them as well as their train. It requires you to remember the point number of each point and switch between operating the train, then changing to set a point, then back to your train, then back to changing the points. It is overly complex and cumbersome and visitors lose interest as the trains are stopped for an inordinate amount of time. A simple momentary contact switch set into the fascia would easily have done the same job, would be easier to learn, and the switches could have been duplicated at a remote location. The other issue I have with DCC is the hypocrisy of its proponents. 'Oh it is simpler.' No it isn't. Look at all the extra power supplies and modules you have had to add just to keep three blocks operating. Plus a control module for every set of points. 'It only requires two wires.' Rubbish! As we see from the underside of your layout, it would have been simpler to wire for block control if you were only going for three blocks. 'It is not much more expensive.' (This is the real kicker.) It is costing me twice as much for a DCC loco over a DC one, and I am fitting the decoders myself. A basic DCC starter kit of power supply and controller cost AUD$500, which is more than I ever spent on all of my DC controllers and switches for block control. Then I am supposed to buy additional controllers for each visitor who might run a train. I have committed to DCC now, but the only advantage I can find is the sound. Everything else is more trouble, more work and more cost.
Hi Grumpy, that was the point of the video. Two wires, my foot! I explain the technical depth required to lead to computer automation and the effort required. It sounds as though your club has allowed someone to ride roughshod over a more simpler solution. Regards Charlie
G'day. Sorry for the rant. I held out for years, but when I finally joined a club I felt like a dinosaur, but now I wonder. Progress is a good thing, but I think some of it is unnecessarily complex.
Dcc advantages over regular DC are HUGE! for starters your trains will run realistic and smoother as its digital, the points along with all lighting of buildings and trains can be automated, theres no reason to use DC today its primitive and unreliable. you can also run loads of trains on the same track in different directions good luck trying that with DC! and dcc can also be wireless, the benefits go on and on, so sorry fella you are wrong. Even a hornby elite has time based automation built in.
DCC a wonderful concept still unfortunately fundamentally flawed. As DCC was invented by an Electrical Engineer in the early 1980's, who had no understanding of railways. He simply created a commercially attractive solution to the major area of resistance preventing model railways becoming a mainstream hobby - i.e the electronics involved. As a result NO provision was made for the most important aspect of real railways, which is the physical inter-action between train movement and signalling. Quite the contrary. DCC has no option but to replace the traditional 12v DC in the rails, with 16v AC, as only AC (Alternating Current) can carry messages between the controller and the train or accessory "chips". In other words you can now move numerous trains simultaneously in any direction you like and even have head on crashes, which goes against the most fundamental safety rules of the real railway. 12v DC wired layouts won't allow head on crashes simply because DC ensures all locomotives go in the same direction, so it does at least start by complying with one of the most important real life safety rules - to prevent head on crashes. There are a number of manufacturers who provide DCC accessory chips that will operate signals. But it is impossible for these "signal controlling chips" to actually operate the signals in a real life manner. Why? Because these "signal controlling chips" cannot know what track layout you have, or detect the presence of trains in relation to the position of ALL the relevant signals. Signals in real life are inter-linked either mechanically (semaphore signals) or electrically (colour light signals). Why?. Because train drivers need warning signals usually a mile or so in advance of any red, or it will be impossible to stop a train in time. This problem of inter-facing the trains to the signals in a realistic manner using a Digital system, was soon recognised. But the solution is that computers are now needed along with a comprehensive understanding of both electronics, and real life signalling. This of course defeats the simplicity of DCC and increases the costs still further. It should be added that commercial DCC is itself between 100% and 300% more expensive than traditional 12v DC wiring methods. Realistically the only way to construct a true model railway as opposed to a toy train set, is to have signalling that works in a real life manner. The only way to do this is to have real life type "track circuits" which provide the inter-face between train and signals. The only way to do all this cheaply is to use a 12v DC system. As 12v DC has the advantage due to its electrical nature of accommodating two separate supplies in the rails (one to move the trains and the other for the track circuits) without creating an electrical short circuit ! The bottom line therefore is that while DCC may seem attractive (although more expensive) it simply prevents a recreation of a real railway in miniature due to its serious technical short comings.
Hi TD, this is clearly something that you feel very strongly about. As you’re aware I’m a DCC enthusiast and it was sound fitted locos that brought me back onto the hobby, post military retirement. I believe that must give ourselves room to develop our hobbies and only offer advice and not criticism, which ever system, scale or gauge we adopt. Regards Charlie
As both a qualified train driver and railway mechanical engineer, and a long time model railway professional, obviously we are talking hobbies here.... But if DCC does not get its act together, you may find it suddenly vanishes off the market. There are already steps by certain others dissatisfied with the fundamentals of DCC, to correct DCC's major failing, the lack of inter-face between train and signals. Read on... Fleischmann spent roughly £2 Million developing a major change to DCC to encompass the real life inter-face between trains and signalling, by incorporating this technology in the master controller. This was unfortunately deemed "non standard" by the large and powerful NMRA and therefore would not have been accepted in the USA, a major market for Fleischmann. The result Fleischmann gave up and sold out to Roco. No one is therefore likely to attempt again to solve the fundamental flaw in DCC. Currently MERGE is one of the only systems available (using digital chips) which can provide the missing technology. But because this isn't manufactured and packaged by a major model railway company, there is still a lot of wiring the user has to figure out. If that changes then DCC may rapidly die ! Currently this all means people like myself with a large complex 4 track mainline exhibition layout cannot use DCC even if we want too, assuming that you understand how real railways operate. The solution to the train signalling inter-face problem can be solved quite easily with a 12v DC layout using nothing more than relays, and the necessary real life type track circuits, which require only a piece of wire to create each track circuit on a 12v DC layout. So its also a very cheap option and solution, although laborious to add all the extra wiring and plan all the real life type interlocking that the relays must enact. On a large complex layout with numerous junctions and crossovers. The necessity to protect your models from crashes and expensive damage, equates to the real world where they have safety systems in place to prevent real trains crashing and killing passengers. Signals therefore cannot be cleared if the route is not set, and all other signals for any other conflicting routes are locked at red. Onboard Automatic Warning Systems (AWS) of various types ensure drivers don't crash red signals. On a model layout preventing operators crashing red signals is easily solved (on 12v DC layouts) by the relays which select which colour or position each signal is displaying, and can also automatically cut power to the track ahead of any red signal simultaneously. So preventing a train going more than a loco length or so beyond a red. Further each signal can be realistically inter-linked with other relevant signals as in real life. Example: As a model train passes each signal it passes over a track circuit (in one rail) and returns that signal to red, and switches off a section of track to prevent a following train crashing the red. Once the train passes a following signal it changes that one to red, and releases the previous signal to yellow. All done simply using 12v DC relays, and track circuits. Now just imagine having all that ready made and ready to simply add alongside all the other accessory "chips"with DCC. DCC would then become a genuinely realistic option, mimicking real life operation and preventing sleepy operators crashing and damaging your expensive models ! The Duke 71000

chocolate block connectors - lovely word!
Tastes good too!
They have had that name since at least the 1950s (when I started my apprenticeship) Can't remember what they tasted like though..
This is all true! dc or dcc good wiring at regular intervals of the track is essential for perfect running!
Sadly, I actually enjoy wiring!
Same here m8, i have ocd about these things and will triple check everything lol! but yea im looking into full PC automation using N gauge, ive heard the bachmann dynamis ultima can do this?
Hello, Charlie. Very informative video. At the age of 73 I am about to build my first layout. Is it possible for a engine, not fitted with decoder, to run on a DCC track and, for a engine fitted with a decoder, to run on a none DCC track? Thank you. Kind regards, Tom.
Been subbed for ages on my own channel but just subbed on my railway channel.
Working my way through the videos in no particular order. Really enjoy the way you film and it's good when you make mistakes and admit it then show how to sort the problems 👍🏻
Keep up the good work.
Thanks HMR, I’m so pleased that you enjoyed them.
Nice informative video Charlie, yes I use pretty much the same two wires also!
Michael
Hi Michael, I'll bet yours are Red and black too. Keep it up with WestBlythMPD. Regards Charlie
Hi Charlie, yes Red, Black, Green, Yellow etc etc, West Blyth is ongoing albeit slowly when my back and money allows.
Michael
Good afternoon in regards to wiring do what guage do you use for all the different bits and bobs i.e power ect.When wiring a dcc chip to a loco what wiring would you use for that hope all is well
Ken
Hi Ken it’s very difficult to suggest which cable sizes you should use, it’s all to do with how much power you intend to draw. I suggest you get in contact with James from DCC Train Automation. He will give you all the assistance you need. Regards Charlie
@@ChadwickModelRailway thanks very much I will do indeed
(Edited Update)... Wow, plenty of spaghetti there to feed you for a week if you could eat it, LOL. Tho with you upending the boards like this and have shown how you have kept it neat and tidy from one section to the next is impressive Charlie. Do you have OCD... LOL. No with my early days doing Electric Engineering and Electronics back in the mid-80s. Taught me how to control the flow of wiring to different sections and to have every aspect of it neat and tidy, especially for fault finding. At times it can look bewildering, but colour coding and labeling everything makes it a lot simpler to follow one end to the next.
This is a must in the IT Depts (that I worked in the NHS) for servers etc as your not working between two baseboards next to each other, but from room to room, building to building. So a label like B2S15IO31PC101 would be Building #2 - Server #15 Input/output network socket 31 to the PC #121 (1st floor on computer 21). Long Labels they maybe but if you're at B10S09IO17PC523 you know where to go.
Therefore logically baseboards can be the same B1PM05S09 (Baseboard #1 - Point Motor #05 - Signal #09) even to the extent that the label points out both ends of the cable going from and to elsewhere (as above) would be B1PM05S09 - CP01TB03SW19 (Control Panel #01, Terminal Block #03, Switch #19). Long-winded maybe, but useful in a wiring diagram in your layout folder that has six A4 pages for a 6x baseboard layout.
Edit Update: Oops I forgot to say that the label L1 closest to the T1 terminated end is that location. The 2nd label L2 is then the T2 terminated end away from this point to its location.
T1 12v @ ----- wire/cable ---- @ switch T2 etc, etc, etc
I think I got that right... LOL, anyway, hopefully, that will help any beginners with their designs on paper to draw the layouts connection points of wiring and to label the physical wires on the baseboards.
To make the labels: just cut an average address label into strips to suit your needs. Then wrap it around the wire as you would with a Loaf of Bread sticky Sealer tape and write the info on it. If printing the info on a sheet of A4 and cutting them out, but remember to leave the same length of blank space after your text and cut out. Add a few extra spaces (4mm) to cater to the thickness of the wire. Now place the cut-out strip of text paper and lay it flat on a clean area of your work table. Now get your roll-off Sellotape and pull a cut strip of it longer than your label, and place it lengthwise on top of your label, but centered the best you can top and bottom and stick it down gently on top. Next is to peel it up again with the text stuck to it and wrap it around your wire so that the sellotape sticks to its self (like the bread sealer). Lastly, cut away the excess clear sellotape leaving 1-2mm around the edges of your label to stop it from opening and falling off.
My notes are even larger than 6 pages. Each piece of electronics also has a page! Good notes are essential. I’ve learned the hard way. After a couple of weeks away, I returned to my model Railway club. I was shocked to find that one board had been wired completely with orange cable!
@@ChadwickModelRailway Yeah it is a matter of it being kept as a KISS (Keep It Simple Stupid) plan. Orange is a favourable colour over here in Belfast... LOL even LOL (Orange Lodge Halls IDs e.g. LOL45 etc). Funny thing if I built a prototypical layout of the NIR from the 70s in Summer. I would have to paint the house Gable Walls with Murals and the kerbstones in Red, White and Blue too, LMFAO.
Got it John
@@ChadwickModelRailway Actually Charlie that would make a good short video on Labelling For Layouts film on here for your Subers.
Very impressive! I am planning to go DCC for the first time, although I have no desire to go full automation with computer control; too much of a "Luddite" for that!! Being able to control more than one loco' at a time, and the sound functions is what interests me, so we shall see how things progress from there. Another excellent video which has proved useful to me as I plan the layout....Cheers!!
I’m so pleased that you have found it useful.
The thing is though charlie, it really can be as simple as 2 wires going all the way up to hundreds of wires, One thing i cannot grasp is how they can charge £300 for TrainController software that's only a 16MB file! I know you only ever have to buy it once but damn man, are these people living 20 years in the future or something? I sat down last night with a calculator to add up how much everything i need would cost in N gauge, at the moment i'm up to £2,050 and counting! I'm going for the digikeijs dr5000 system, it does absolutely everything, Anyway charlie your videos are the best on youtube
Good luck with your automation and do keep this community posted with your progress. There is of course, JMRI which is free but apparently, it’s a little less user friendly.
Regards Charlie
Wait til you start buying locos and carriages!
I'm doing the same. My new layout for DCC is quite challenging and I am no electrical genius. MYT issue is which DCC system to use.
Hi Charlie, Great video, I use Railmaster and like you say one short and everything stops. I am a pensioner and on a budget, so I have to use what I can afford. thanks for sharing .......John.
So glad that you enjoyed it John.
Hey, I’m just starting my dcc layout and like the idea of having the separate power districts to prevent the whole layout shorting out if I have one.
I was looking at those PM42’s and was wondering if they work with other brands/products.
I want to keep things as simple as possible for now and I’ll be running from a hornby select controller to start with. In my mind I’d be putting the main power into the PM42 and running the BUS wires from them into the separate districts. Would this work 😅
The PM42 is ideal for Digitrax layouts.
However, there are better solid state options that are cheaper. Give James a call at DCC TrainAutomation
01823 429309.
Informative, professional, impressive
I’m so pleased that you enjoy such entertainment Cullen, you missed out brilliant. Love to all. Charlie.
Excellent video, Charlie.
As others have commented, neatly wired and strapped into harnesses, and that makes the wiring diagrams so much more important.
Do you think there is a benefit to using different wiring colours, or do the diagrams look after all that for you? Diagrams detailed down to pin level for the controllers, and “pin level” at the solenoids and lights? An image or example of the level of detail you have found effective would be most helpful, please.
As usual, clear and entertaining, so looking forward to the next one!
Regards, Tom
Hi Tom, I'm shooting the next video now which explains my wiring plans. I do hope you like it. Regards Charlie
Hi Charlie. Pined type Choklad block can i you give a link for these. i live in Denmark, we don´t that type ? love you Channel and are learning a lot about modeltrains. Thanks Flemming
They are all listed in the “show more” tab of the latest video, number 115.
Charlie , a question for you can you suggest a power unit for a dc layout spread over 2 x 8' x 4' boards , this will need to cover up and down line outer circle plus fiddle yard . I need to have constant voltage over all aspects , this layout will hopefully be updated to DCC late 2021 early 2022 . Hope you can help
Best contact DCC Train Automation. They have a better appreciation of what’s currently available.
Hi. So I'm about to (once the garage is cleared) embark on an insane project and having watched a lot of your stuff as well as others I am heading down the Digitrax route. I'm intending to use some computer control (currently JMRI most likely as I can run that on a Pi) but currently just planning stuff. However have hit on an issue that I just cant get my head around as I cant find the info: The numbering / Board IDs etc of all the devices.
Going to have PM42s DBL168s DS64s (about 24 of the buggers so may need a new mortgage) and an SE8C. I *think* all the board ids can overlap between devices, so there can ba a 42 that is a 1, 168 that is a 1 etc. But, particularly with the block detection, switches and light outputs of the SE8C there seems to be some concern about overlap.
Have you any idea what can overlap, what cant overlap, and any hints on numbering all these devices!
Cheers and loving the channel!
Ian, you have no worries on this one as I'm sure that can have the same ID.
When building this layout, I called the first board, Board 1.
So the DS64 numbers are 101 and 102.
The points also start with a 1. 11, 12, 13 etc.
The BDL168 is 101
On Board 4 they are 401 and 402 etc.
You just need a routine that works for you.
When it comes to computer inputs it will ask for the DS64 number and its point numbers.
Good luck, its a long journey!
@@ChadwickModelRailway cheers! Yeh definitely a long term project. Partly due to time but mostly due to cost!
Nice job!
Thanks MTA, regards Charlie.
This is awesome

Beyond me mate.
Cheers for the video, I am just starting my layout, and wiring is one of the things I am not looking forward to.
Good luck with the wiring Geoff. My next video has more basic wiring included. Regards Charlie
Appreciate Video clip! Apologies for butting in, I would appreciate your initial thoughts. Have you ever tried - Januke Henatalie Formula (google it)? It is a great exclusive guide for operating a DCC model railroad minus the normal expense. Ive heard some interesting things about it and my work buddy at last got great results with it.
Another great video Charlie. I really like them yellow tags on the wires. Where did you get them from? Thanks.
It was a random purchase on eBay but I’m looking for something better.
Chadwick Model Railway thanks Charlie
Great vid Charlie, think I'll have to stick to my old analogue gaugemasters- as my late Grandfather used to say "it's a bit too testicle for me" Regards Terry.
Sound advice I’m sure Terry
@@ChadwickModelRailway Hi Charlie I am running some railway beginners workshops in April in Denham west London would you be interested in running one on electrics? stephenbeamon@gmail.com Thanks
I would be interested to find out how often you set it up at an exhibition and have to do some form of troubleshooting to make it work properly vs how often you just set it up and enjoy? Cheers, Michael
Hi Michael, it ran pretty good to be honest. The only drawback was having the rails cross the board join at an angle. A schoolboy error really. Regards Charlie
So much about DCC confuses me. How are the seperate power districts seperated; is that simply with insulated rail joiners? And, where do boosters come into play?
Hi Gabe, I think that you are over complicating DCC. Boosters are only required on large layouts that need more power than your system can provide. Most controllers produced 5 amps and that is normally ample.
Power districts are also not essential and need to be planned at the initial wiring stage. Insulated rail joiners are only normally used when electrofrog points are installed.
The shop “Digitrains” can offer unbiased advice.
Regards Charlie.
Hi Charlie. Just started out a simple layout with my son. Great videos with a lot of insight! I'm struggling at the moment with the wiring side of things though. Currently running DC. Can I connect 2 separate tracks together without any issues/ short circuits?
Thanks in advance.
Paul B.
Yes Paul you can but if you’re running two locos they will run in unison.
Because I'm powering the track not the loco. I may convert my locos to DCC then.
Thanks!
Can I wire in more than 1 track piece on DC and have a bus unit or will that take to much power away from the controller??
Good day to you ,
Can you tell me what type of cables you used, feeders, points and block detector, in mms? I see you use Digitrax.
Thanks and your videos are great help, keep them coming.
Hi Dylan. I use 7 x 0.2mm for droppers etc and a 5 amp cable for the Bus.
Very interesting, and a great video. I was wondering if you were able to do a video regarding block detection and signalling wiring? I.e. I'm always impressed when the trains are able to pull-up to a station or signal but not 100% on how and where to place the breaks or detection for circuit features
Hi Steve I will do in the future when my layout reaches that stage, it might be some time!
Regards Charlie
i have models that are over 30 years old can go dcc or do i have to stay with dc
Some older models do struggle with the modification James.
@@ChadwickModelRailway thank you for the reply i am thinking of probably going with half dc and half dcc so i can run both dcc and the older 1980s lima locos i have. thank you for the help.
Charlie, I have been greatly enjoying your videos this year. I am currently planning my first DCC layout. Whilst most of the subjects you cover I understand the electrics side of it I really don't understand. Can you recommend a book for a complete DCC wiring guide please, Thank you Stephen Allen
Thanks Stephen I’m so pleased you enjoyed the channel. I’m sorry I can’t recommend a D cc wiring book but I’m sure there must be some on the market. Take care regards Charlie
Just a question. I own HO scale trains. I've been going DC. Now, I'm considering DCC. Question: say I have 4 trains: the locomotive, freight, tanker and caboose. I realize that the locomotive MUST be DCC-ready but must the other three be DCC-ready? Sorry for the dumb question. Can anyone help?
Hi Obeeone, yes DCC is all or nothing.
You need a DCC controller which will deliver 15v AC. DC layouts use 12v DC.
Then you have to fit a DCC decoder into every loco. It’s a pricy conversion but could be worth it depending on your aspirations. Hopefully you have subscribed too.
Nice video and thank you for subscribing to my channel . 😃
I’m so pleased that you enjoyed it. Regards Charlie
Charlie. Any chance you can at some point do an idiot’s guide for those of us who feel we have made the mistake of opting for DC and realising we have rather opted for the Stone Age solution?
I shall consider it Alan, but there are dozens of videos on TH-cam which cover this subject. Regards Charlie
Hello, I wondered if you could give advise on equipment I need to run Traincontroller ( Silver) such as:
Command station etc.
I would have:
1. around 20-3O blocks
2. 30+ turnouts ( servo type )
3. Signals 2 and 3 aspect not sure how many yet.
Would be possible if I could contact you for more details..
Many thanks
Wow Alan, what a question! I use Digitrax but there are others such as Lenz and I think NCE can do it as well. The buget that you will require is not small. A Digitrax system cost around £350. To carry out block detection, a BDL168 detects 16 blocks and retails at £135. TC Silver costs around £350. I suggest you find Rudy, (rudysmodelrailway) on TH-cam. He has a great series of videos and explains in great detail, how TC works. You might also phone Digitrains and ask for their guidance and prices. Good luck. Regards Charlie
Hi have you ever done a video on DC wiring a layout please
No John, I’m sorry but I haven’t. Regards Charlie
Super fantastic video! Very informative and it does give a good insight to how, if wanted, to advance your layout. A question if I may, as you said you are using a few Seep Solenoids, have you been able to get these to work with the DS64? I have struggled with this and so have others and I would very much appreciate any information or help on this matter. If you message me I am happy to provide my email for easier communication. Thank you! Des
Hi Des, I have had no problems at all with SEEPs. I only install them when the original Peco motor/switch became problematic.
I imagine that you have electro frog points and have programmed your DS64 correctly.
I can email you a photo of the wiring of the SEEPs and DS64, if you send me your email address.
I can delete the email address once your message arrives.
Regards Charlie
Got it Des.
Super thank you Charlie.
on my analogue Model Railway technically I can run 10 trains at one time , However they will derail and Crash . I can on my own run 3 trains safely with a 4 train shunting and running round etc.my question is if I convert my 250 powered 00 trains will DCC Stop them derailing . of course I would have to become a millionaire to convert.
Yes, with Train Controller Gold and heaps of cash, anything is possible!
I understand that it is 'possible' to control points at the controller, I just don't understand why anyone would do it. I am a member of a club which displays a simple exhibition layout. The 'expert' who set up the DCC insisted on controlling the points using the Digitrax handsets. He understands it, but he does not turn up to operate it at exhibitions. Everyone who does has to learn the controls and then operate them as well as their train. It requires you to remember the point number of each point and switch between operating the train, then changing to set a point, then back to your train, then back to changing the points. It is overly complex and cumbersome and visitors lose interest as the trains are stopped for an inordinate amount of time. A simple momentary contact switch set into the fascia would easily have done the same job, would be easier to learn, and the switches could have been duplicated at a remote location.
The other issue I have with DCC is the hypocrisy of its proponents. 'Oh it is simpler.' No it isn't. Look at all the extra power supplies and modules you have had to add just to keep three blocks operating. Plus a control module for every set of points. 'It only requires two wires.' Rubbish! As we see from the underside of your layout, it would have been simpler to wire for block control if you were only going for three blocks. 'It is not much more expensive.' (This is the real kicker.) It is costing me twice as much for a DCC loco over a DC one, and I am fitting the decoders myself. A basic DCC starter kit of power supply and controller cost AUD$500, which is more than I ever spent on all of my DC controllers and switches for block control. Then I am supposed to buy additional controllers for each visitor who might run a train.
I have committed to DCC now, but the only advantage I can find is the sound. Everything else is more trouble, more work and more cost.
Hi Grumpy, that was the point of the video. Two wires, my foot! I explain the technical depth required to lead to computer automation and the effort required. It sounds as though your club has allowed someone to ride roughshod over a more simpler solution.
Regards Charlie
G'day. Sorry for the rant. I held out for years, but when I finally joined a club I felt like a dinosaur, but now I wonder. Progress is a good thing, but I think some of it is unnecessarily complex.
Mate its done because of computer automation! you can let your pc run the whole layout and just sit watch and relax with a coffee!
Dcc advantages over regular DC are HUGE! for starters your trains will run realistic and smoother as its digital, the points along with all lighting of buildings and trains can be automated, theres no reason to use DC today its primitive and unreliable. you can also run loads of trains on the same track in different directions good luck trying that with DC! and dcc can also be wireless, the benefits go on and on, so sorry fella you are wrong. Even a hornby elite has time based automation built in.
Seems like a sensible comment that should be read before anyone embarks on a DCC project.
Excellent video, but having seen all those wires - and being absolute rubbish at electrics - I have been scared-off and will stick to analogue.
Hi Bryan, I’m so pleased that you enjoyed the video. It’s only that complicated to enable computer control. Come on and go DCC. Regards Charlie
DCC a wonderful concept still unfortunately fundamentally flawed. As DCC was invented by an Electrical Engineer in the early 1980's, who had no understanding of railways. He simply created a commercially attractive solution to the major area of resistance preventing model railways becoming a mainstream hobby - i.e the electronics involved.
As a result NO provision was made for the most important aspect of real railways, which is the physical inter-action between train movement and signalling. Quite the contrary. DCC has no option but to replace the traditional 12v DC in the rails, with 16v AC, as only AC (Alternating Current) can carry messages between the controller and the train or accessory "chips". In other words you can now move numerous trains simultaneously in any direction you like and even have head on crashes, which goes against the most fundamental safety rules of the real railway. 12v DC wired layouts won't allow head on crashes simply because DC ensures all locomotives go in the same direction, so it does at least start by complying with one of the most important real life safety rules - to prevent head on crashes.
There are a number of manufacturers who provide DCC accessory chips that will operate signals. But it is impossible for these "signal controlling chips" to actually operate the signals in a real life manner. Why? Because these "signal controlling chips" cannot know what track layout you have, or detect the presence of trains in relation to the position of ALL the relevant signals. Signals in real life are inter-linked either mechanically (semaphore signals) or electrically (colour light signals). Why?. Because train drivers need warning signals usually a mile or so in advance of any red, or it will be impossible to stop a train in time.
This problem of inter-facing the trains to the signals in a realistic manner using a Digital system, was soon recognised. But the solution is that computers are now needed along with a comprehensive understanding of both electronics, and real life signalling. This of course defeats the simplicity of DCC and increases the costs still further. It should be added that commercial DCC is itself between 100% and 300% more expensive than traditional 12v DC wiring methods.
Realistically the only way to construct a true model railway as opposed to a toy train set, is to have signalling that works in a real life manner. The only way to do this is to have real life type "track circuits" which provide the inter-face between train and signals. The only way to do all this cheaply is to use a 12v DC system. As 12v DC has the advantage due to its electrical nature of accommodating two separate supplies in the rails (one to move the trains and the other for the track circuits) without creating an electrical short circuit !
The bottom line therefore is that while DCC may seem attractive (although more expensive) it simply prevents a recreation of a real railway in miniature due to its serious technical short comings.
Hi TD, this is clearly something that you feel very strongly about.
As you’re aware I’m a DCC enthusiast and it was sound fitted locos that brought me back onto the hobby, post military retirement.
I believe that must give ourselves room to develop our hobbies and only offer advice and not criticism, which ever system, scale or gauge we adopt.
Regards Charlie
As both a qualified train driver and railway mechanical engineer, and a long time model railway professional, obviously we are talking hobbies here....
But if DCC does not get its act together, you may find it suddenly vanishes off the market. There are already steps by certain others dissatisfied with the fundamentals of DCC, to correct DCC's major failing, the lack of inter-face between train and signals. Read on...
Fleischmann spent roughly £2 Million developing a major change to DCC to encompass the real life inter-face between trains and signalling, by incorporating this technology in the master controller. This was unfortunately deemed "non standard" by the large and powerful NMRA and therefore would not have been accepted in the USA, a major market for Fleischmann. The result Fleischmann gave up and sold out to Roco. No one is therefore likely to attempt again to solve the fundamental flaw in DCC.
Currently MERGE is one of the only systems available (using digital chips) which can provide the missing technology. But because this isn't manufactured and packaged by a major model railway company, there is still a lot of wiring the user has to figure out. If that changes then DCC may rapidly die !
Currently this all means people like myself with a large complex 4 track mainline exhibition layout cannot use DCC even if we want too, assuming that you understand how real railways operate. The solution to the train signalling inter-face problem can be solved quite easily with a 12v DC layout using nothing more than relays, and the necessary real life type track circuits, which require only a piece of wire to create each track circuit on a 12v DC layout. So its also a very cheap option and solution, although laborious to add all the extra wiring and plan all the real life type interlocking that the relays must enact.
On a large complex layout with numerous junctions and crossovers. The necessity to protect your models from crashes and expensive damage, equates to the real world where they have safety systems in place to prevent real trains crashing and killing passengers. Signals therefore cannot be cleared if the route is not set, and all other signals for any other conflicting routes are locked at red. Onboard Automatic Warning Systems (AWS) of various types ensure drivers don't crash red signals.
On a model layout preventing operators crashing red signals is easily solved (on 12v DC layouts) by the relays which select which colour or position each signal is displaying, and can also automatically cut power to the track ahead of any red signal simultaneously. So preventing a train going more than a loco length or so beyond a red. Further each signal can be realistically inter-linked with other relevant signals as in real life.
Example: As a model train passes each signal it passes over a track circuit (in one rail) and returns that signal to red, and switches off a section of track to prevent a following train crashing the red. Once the train passes a following signal it changes that one to red, and releases the previous signal to yellow. All done simply using 12v DC relays, and track circuits. Now just imagine having all that ready made and ready to simply add alongside all the other accessory "chips"with DCC.
DCC would then become a genuinely realistic option, mimicking real life operation and preventing sleepy operators crashing and damaging your expensive models !
