For my fellow foamers (railfans), I'm putting together this short video series on how to read North American Railroad signals. In this part 1 I cover the foundational 3 light system from which we will understand the rest of the signals.

This is the clearest, simplest explanation of signaling I've found. Thanks!
As a train driver in UK, I find this type of signalling unnecessarily complicated compared to what we have here, but it's a great instructional video and interesting to see how other countries do it!
We have a two aspect system in Melbourne Australia , likewise top aspect is normal speed clear , normal speed warning or stop , the lower aspect is medium speed clear , medium speed warning or stop . The only low speed signal is a low speed caution (small yellow/amber light) , this allows a driver to trip through a red home signal into a stabling siding , this can also be a dwarf signal post reading purple or yellow , yellow is clearance to shunt onto the main line , purple (looks blue) means the points (switch) have not been set to run into or out of a siding , thus purple is read as the same as red
Wish they had such a clear presentation for signals such as this one when I was training to be a brakeman! Also they have simplified the names of the signals as what is now a “clear to stop signal” used to be called “approach signal.” Good job!!!
Thank you for the very good explanation of the signal system in Canada. I play Train Sim World and have not understood it in the simulation, despite the manuals. Now I finally have an idea how this system works.
Fascinating. It seems to be a lot more complicated than the British 4-aspect colour light signals, but if it works for North American railroads, then it would be wrong to say that one system is better than the other. Thank you for this excellent presentation.
The presentor of this material has done an absolutely excellent coverage of the generally unappreciated, yet very powerful, concept, of RTC which is essential, not only to safe rail operation, but equally importantly to maximize the capacity of the track plant, i.e. by optimizing the headways. I would like to use the opportunity to add a small comment: the "Restricting Signal" is often referred to by train crews as a "Dirty Yellow". Excellent presentation!
This helped a lot, I’m starting my training to be a train conductor for CP next week and wanted a head start and I came across your video. You’re an excellent teacher thx for the upload
Awesome! Best of luck to you starting your career!
Norac signals are basically the same, except what you call "clear to stop" we call "approach". Good stuff!
As a railway photographer this great informative video is a great deal of help! You are now my new best friend! Thank you!
This is literally one the best and most informative videos I have ever watched.
Awesome explanation, man!
Thanks so much for this!! What a wealth of information for not just railfans - but for Model Railroaders!!!
.... We spend a lot on various signals - it's good to actually know how to *USE* them!!! ;)

Pay no attention to a foamer a foamer is a know it all
I need to see this video YEARS ago... thanks for posting.
Thanks for the info, I have been wondering about the signals on my commuter rail since I started using it, this is the best explanation (the whole series) I have been able to find. Well Done!
As a player of Train Simulator and watcher of over millions of train videos on TH-cam, the only signal function I was always capable of automatically recognizing was a simple green signal turning into a red light once a train passes it. I recently just figured out that red signals turn yellow and then green when a train passes the signal blocks beyond them.
Thanks. Very informative and easily explained. I particularly liked the fail safe coverage. Please post more about railroads. Thanks again.
This is the best explanation of signals I've ever come across. Well done. Looking forward to watching the rest of the series. Well done.
Thank you SO much for not ruining your videos by using heavy- metal guitar or techno......you have no idea.....
Thanks for all this information! I've wondered for years what they meant in different configurations. I had to learn what they meant on the Chicago Transit Authority when I worked on the El-Subway system, but they were relatively simple.
great video. great pace. you introduce a concept, explain it, link it with other concepts, and review. You build on that concept to introduce next concept. well done. I was feeling a bit overwhelmed reading the Transport Canada manual... this is stupid simple! Thanks Bud!
Best intro to canadian signal systems out there . Well done ! Can't wait for more to come . Clear & understandably basic to prepare for more complicated signal to come in videos to come. Well done !!!
Thank You Ian... I think~ I'm in the process of placing signals on my layout and your videos have given me a much better understanding of signalling. unfortunately not as simple as I thought!! None the less a very helpful series of videos I will have to watch several times.
You just earned yourself a subscriber. Now I understand why the US/Canadian signalling was built the way it was built and improved my opinion on it
I love how you teach these courses. You make it interesting, easy to follow along, and easy for all ages. You need to do more of these educational videos. Thanks again.
Hi Ian, thanks again for this. Just back from western Canada vacation. I learnt a lot from your videos which proved very helpful over in Canada. Clear to stop I found an interesting name for a signal, got a laugh out of it.
When asked how difficult is it to drive a train I always said "Driving them is easy. Making the buggers stop is what turns your hair grey."
True dat!
Holy shit.....just bought trainz railroad sim 2019 and was directed to this video by a friend of mine....im pretty sure ths little light bulb in my brain just burnt out....no fail safe system in my brain.....GREAT VID...LOTS OF DETAILED INFO.....but im pretty sure im gonna have to get a piece of paper and colored pencils for notes.....
I learned alot watching this video and I'm not afraid to say I thought these train signals work like regular traffic lights. However I can can see that the way they interpreted aren't not the same at all. I'm happier to know my knowledge is improved, because of this video. Thanks for sharing it!!👍
thanks for this: it's much clearer than in the CROR handbooks
I’m a retired locomotive engineer and I really enjoyed this video. You said it very well. Your Canadian signals are a little bit different than ours but basically say the same thing. Thanks 👍👍👍❤️
I operate LRVs in Kitchener Waterloo. Going under a bridge where freight passes, I always glance up at their signals, slightly confused. I think you're educational vid has cleared this up for me! Interestingly as well, when I saw the amber LED shown in your vid's light standard, I immediately interpreted "diverge". Lol. For me, an amber aspect is a change in track, a diverge from one track to another. Must be mindful of point position, therefore. Similarly, a green aspect indicates my route is set to normal, switches are set to normal so I'm on the straightaway. A red aspect or light: ALWAYS STOP!! In LOS, we use the lunar aspect or that bluish, whitish light. A vertical bar indicates a non permissive or STOP where by contrast the vertical lunar indicates proceed. A flashing horizontal lunar is preemption, indicating I'll get my proceed shortly. And so I digress....would love to see you do a video on switches!! You'd be a great facilitator anywhere where rail teaching is needed!! 😊😊😉
I’m studying to be a conductor at the moment. Being a rail fan and having a potential career with the railroad has me ecstatic 24/7.
Right on!
Thank you, thank you, thank you! I've been so confused about North American signal aspects (British route signalling, here), and what each position represented. You explained it perfectly, and clearly. Especially the high, medium, and slow-speed *positions*! Makes so much more sense, now.
Im gonna ruin your day here: he only gabe the basic signals, there's probably another 100 or so signals with two permissive colors (green/yellow) and the whole middle medium, low slow trick gets thrown right out the window, and the colors represent the speed.
IMHO, so far, THE BEST explanation video ever.
I'm a german traindriver and now I can start working in Canada :D The basics are quite easy, I like your system!
Awesome video - very clear and understandable - much better than the short version I've heard (so far) in Trainz 2019 :) Now it makes sense. Thank you :)
This is awesome! If you ever get the notion to get off the rails, you should consider teaching (this or any other subject matter). You are very concise. Some other comments below indicate some minor omissions or factual errors, well.... we're all human, can't be correct all of the time. Thanks, Ian ! Safety First, Last, Always.
Nice logo! CP Shipping?
@@jamielacourse7578 Actually, was CP Transport/Express. Ground transport by rubber tire. CP Ships logo was green.
Have jus come across your videos and channel. Thank you. Clear presentation and illustrations and as one who has traveled many of the long distance routes in Canada in the observation car, I appreciate this information.
Hello Ian. You are a railway enthusiast and it shows. Good way of explaining. I'm positively sure it does increase railroad safety by sharing how it works to the community. :)
This is an excellent video. You are a natural at teaching this material, sir. Very well done!
Great video, thanks for the very clear explanation of the three light railway signaling system.
Many thanks! Been looking for someone to give a concrete explanation of this. Also I like how you explain the differences between the U.S. and Canada types. Much appreciated!
Thanks for explaining these signals on CN. It's beginning to make sense.
Dude you are an amazing teacher!
Perfect clarity 👌
When from dumbfounded to needing more information.
Will probably watch this and however meny parts are next a few times
Hello Ian! Just wanted to say, this is literally the first video I've seen on YT that's persuaded me to actually log in and rate it... Top marks, for both content and presentation. Thank you!!
There's a fourth aspect on some position lights. The restricting aspect is a diagnal line 90 degrees opposite of the approach aspect.
Thank you. this had been the most informative video yet on how to pass the signals in train simulator.
You did a nice job explaining this. You must have teacher genes.
A good explanation of CTC speed signaling, which is widespread in east and northeastern US. Western US railroads typically use route signaling where CTC is employed. And most recently, speed-enhanced route signaling is used, still with two aspects, but with specific speeds assigned to each "approach xxxxx" indication.
Super video and well presented. Really helped a novice understand. Thanks.
I've been wondering what the 3 lights on the tracks meant for years. Thanks for explaining it!
This is a very good, and excellence teaching tool for those whom wanted to become a freight conductor and need a refresher in signal training. Thank you so much for this. :) :) "I had a little problem remembering the signals".
That's the most straight-forward explanation I've ever seen.
Thank you !
Interesting to see how different signal systems work. Here in Florida, the FEC uses a slightly different system of signals. The high clear and high yellow are the same, of course. FEC's middle green indicates a diverging clear. A low clear sometimes indicates a clear diverging through a siding instead of the main track when no other trains are present, such as going around a slow order.
Thank you for the primer on the Canadian signaling system. 👍
That man is very smart about trains and signals.
Wow, fantastic video! This explains the why so well.
It's really a nice video and good explanation. Sadly, it is much more complex than the railway signal in India.
1) Green: track clear
2) Yellow: except next signal red and prepare to stop
3) Double yellow: except next signal single yellow and prepare to slowdown / trian will move to side track (if double yellow at home calling signl.)
4) Red: stop
Wow finally i got it how all that works, thanks a lot :)
I´m a locomotive engineer in germany, our signals have very little in common with that CN system. We have only one set of green, red and yellow and anything slower than track speed is shown with illuminated numbers 1 to 16, meaning 10 to 160 kilometers per hour.
Wow! Ian Juby the creationist is actually a rail fan and a railway conductor? Who would've known. I just clicked on a set of videos describing signalling and when this one started playing, I thought, "I've seen this guy before". Lol. Small world Ian but not a young one. It really is 4.5 billion years old, dinosaurs never lived with man and sharp teeth are not for chewing vegetation.
At least in this video you aren't spreading misinformation. 🚂
Thanks for sharing. 🙂👌🏼
I really enjoyed your video! Interesting to hear how you have different names for the signal aspects than what we use in the U.S. Hope to see more from you. I wish I had videos to watch like this before I went to work for the railroad.
Great video and very interesting. Your narrating is excellent.
As a friend of mine who used to work for CP said; "If it ain't all red, then it ain't red at all." It can be quite disconcerting for someone who doesn't know the system to see a train flying at a signal with one green and two red aspects.
This is an excellent video ... thank you for posting on TH-cam ... definitely learned some things that I didn't know previously ... thanks again for a great video.
Thank you very much! Best wishes and greetings from Europe!
It remembers me a bit of the italian railroad signals although there are differences!
Thanks for this set of three videos on signals - very educational!
Very well elucidated. Thanks for the information .
That was interesting and very well presented. You gave an excellent explanation. That's a lot of nuances to remember... I'll need to watch it again.
@ 9:40... now there's a curveball signal... here in the states, the LUNAR signal is the restricting signal not the yellow... so that red/red/yellow on the U.P. is, "Diverging Approach Slow: Proceed on diverging route prepared to stop before any part of train or engine passes the next signal. Speed through turnout must not exceed 15mph. Speed to next signal must not exceed 30 mph."... this also underscores the importance of those who travel on foreign roads to HAVE A COPY OF and UNDERSTAND that foreign roads TIMETABLE and signals and ALL of the restrictions on whatever subdivision you are visiting on... i wonder how many railroaders have been canned by dropping the ball on somebody elses' railroad
I agree with the last commenter. A wealth of info on how trains run. Thanks.
Very interesting vedio loved it thanks for sharing have a blessed day/Night
I like the CROR signal names. When I am teaching a new hire, I always explain it as what speed your at now, and what speed after. Clear to stop; clear now, going down to a stop, after passing the signal. Medium to Clear; medium speed now, up to MAS afterwards.
The rail system just fascinates me, Thanks for all the interesting info.
Great video. Better than a book I read dedicated to this subject!
Hi Ian, many thanks for these videos! I really enjoyed them and appreciate the time you took to put them together. Very well presented. I'm heading to Western Canada for the first time (from Australia) in September for some rail fanning the big ticket photospots. This will come in handy!
+SantaFe5811 Cool! That sounds fun! Western Canada is awesome.
I've watched the El and Subway signals in Philadelphia back in the 1980s, and each signal head was a 3-color, shaped like upside-down traffic lights. I'd board a train and do what railfans do, move to the front door and watch from the front end as the train headed down route. I'd see plenty of green signals, until we got into Center City where trains can't move as fast and bunch up. We'd then pass a yellow signal to reach (and stop at) a red. We could actually see the train in front of us, and once it left a station and moved farther away, our light would turn from red to yellow and we'd move. There were plenty of rigged signals too, that had the green light permanently blocked; the signal would read yellow even if clear ahead, to artificially make the train slow down, then on approaching the red signal it would suddenly turn green. Typical SEPTA not trusting their drivers.
tx u so much for sharing this info.. open my mind N can feel what you feel as a railroader.. this video, it's useful enough for me because I'v been working for a project dealing with commuter line.. not as a railroader :-) but as a consultant..
Thank you brother...even railway company training is not as clear as this.
I think the LMS over in the UK trialled a similar system in the 1930s but it was never adopted. We still use route signalling as the basis for all signalling with the speed primarily based on the driver's knowledge of the route, although computerisation has come in as a safety back up.
I start training for CN in a month. This video series has helped me prepare a bit.
can you make a 3rd part soon about the rest of the signals (specifically how to tell if it's a limited signal) such as limited to clear, or slow to limited for example
I wound up transferring to Sioux Lookout, Ontario. It's been nuts having to move and now only gotten internet. Been a month trying to get internet hooked up! So I'll see what I can do here this week.May I ask where you're getting assigned? And congrats!
ah okay :)
assigned to North Battleford, SK
+Southern Ontario Rpooailfan s
Oh Yeah...my kinda video...full of awesome photos and information. Thank you for sharing.
Thank you Ian, well presented and informative. Well done.
Thankyou for this very accurate information. Never fully understood the functions.
Thank you so much for this video! I take the train all the time and was always curious how it works, and thanks to you, now I know! You should consider being a teacher, that was extremely clear and understandable. :)
Thank you for teaching me about those signals! Now I can tell what each one means!
Thanks so much for this! Now I know what those signals mean! I also note that BNSF in Vancouver looks like they use the U.S. signals like you described. So obviously the CN and sometimes CP crews that use this line also have to know these american signals. Also, semaphores were used until recently on CP's Mission Sub at the diamond crossing with SRY in Abbotsford.
Most informative. The signals in Australia are usually of USA manufacture. Either the American or British 'safe working' systems are used.
Hi Ian and thank you very much for the very informative and well done videos. Like you I'm Canadian from Quebec and I love the C.N.R. I plan to model a freelanced model railroad set in the late 50s and based on the Allandale to Penetang subdivision in Ontario. Your videos will be very useful when I plan my signals.
+EMILIEN THERRIEN That sounds so cool! You're gonna post videos, right? :)
+Ian Juby You've got it my friend!
I remember on one of the first signal classes I attended, one guy raised his hand and asked why we needed searchlights... "why do we need to look for aircraft"?! LOL!
Really clear, thanks. I've seen other explanations and didn't get it, but now I do!
This was OUTSTANDING.
Great stuff! I was always curious about those signals so decided to check them out on a whim. Glad I did! You explained these really well! I'm also glad you're Canadian, as so am I. So that was a bonus. ;)
Thanks for the video , and now I can study up for my model railroad operations.
I will give this video a 10 out of 10 good work. keep up the awesome work!!!!!
I always wanted to know this. Thank you so much for posting; thank your great presentation.
Thanks for the rail signal tutorial lesson 👍
Very well organized, informative, and interesting!
A brilliant video - and so well presented too.
Hi Ian, I just came across your channel and I loved this. It was So Very interesting!!! Now I'm going to watch your next video. Have a good day, and thanks again Brother!!!
I don't know why, I still love our Canadian "search light" signals....I guess I just love the signals period, because looks like Christmas always!
