DCC Speed Matching Using JMRI and Accutrack II Speedometer

- I try my best at explaining the methods of simple and complex DCC speed matching using an Accutrack II speedometer and JMRI.
Demonstration is done with HO scale locomotives with ESU Loksound decoders. For other scales or other decoder types/brands, similar steps can be taken to ensure that your locomotives run nicely together. Please note that ESU decoders have an active CV5 (max voltage) regardless if you are using a speed table or not. It has come to my attention that other brands of decoders may have their CV5 become inactive when you select the speed table, in that case you will have to adjust the top speed again in the speed table after you have already done it with CV5.
There's a rendering error near the end of the video causing a red flash, my apologies.

One of the best and clearest tutorials on speed matching i have seen, outstanding great job.
This is by far the best and most comprehensive speed matching how to video out there to date. Awesome job man, and thanks so much for this.
Thank you. This was one of the best explanation and demonstration of speed matching. Well done!
Please, upload again Speed/Throttle/Step/Index conversion chart and CV5 reduction calculator
Excellent video! This will help me a lot. 👍👍👍
Hi from the UK. Found your upload via a link in the latest Model Railroad Hobbyist newsletter. Just what I wanted as I'm about to start speed matching. Thanks Lee
best explanation of speed matching... VERY well done & thorough! thank you
Great video. By far the best, clearest and most helpful video on speed matching. Thank you.
Excellent vid. This is outstanding and shows you put a lot of thought and research into the processes for speed matching. Now I have to go buy an Accutrack II :-)
Intermountain now installs LOCSOUND Decoders. Not sure what they've been running in the past but from the looks of things, ALOT of other DCC locomotives are all switching to the LOCSOUND decoder. I wish the ALL manufactures would switch to LOCSOUND... What a wonderful world it would be!!!
Yes for sure LOKSOUNDare the best
Great video. I really like the spreadsheets. Thanks for making them available.
Very well put video! great job!
great video it will come in handy when I speed match mine fleet.
Good video keep up the good work
Nice job. Thanks so much.
Nice tutorial . Thanks
excellent video thanks
Great video, What do you do with the back EMF and forward/reverse trim settings when starting the process?
I just purchased an Accutrack II Speedometer...has not arrived yet... but definitely bookmarking this video in my Playlist. I will have to take all my other locomotives off my main though or buy some ez-track oval to setup a speed match. Thanks for this... Are you still model railroading? Do not see many recent videos.
I just found your video, looking for the CV5 reduction Calculator. Is it still up on the web ?
Hi, what about the Athern Genesis motor? are they strait line Log or Exponential?
What other popular manufacturers use straight line motor? For example Genesis and Athearn are popular and so Atlas. How would I determine what type of motor they use?
Thank you
What type of speed curve are the athearn locomotives? Straight or curved?
Hi. Great video. Would you hapen to know the max speed out of the box, of the Scale Trains GEVO Tier 4 with sound? I think you and I got them about the same time, August 2017... I'm wondering if I accidentally changed a decoder setting, as it tops out at 82km/h (about 48mph) but people seem to have toem going faster... My speed matching on Locs is to 100km/h (60mph)... -Chris
About 68-69 scale mph if I recall correctly.
Thanks. I need to figure out where in the decoder it has been reduced. Like perhaps a 'locked in' shunting speed... not sure. -Chris
Having issues downloading the two file. I'm only seeing 1 the speed match file.
There is only one file. The excel file contains the two spreadsheets
can you please send me the link for the Speed/Throttle/Step/Index conversion chart and CV5 reduction calculator: as the link does not work.
Thanks in Advance
Is the spreadsheet file still available? The link is not working.
Any ideas on speed matching with the throttler going to 126 for 128 speed table?
As in 126 scale mph? Most HO scale models are not capable of going that fast. You can speed match each step for half a mile for a top speed of 63.
@@DBRXCustomRailroadModelsSorry. Talking about the throttle % going up to 126% instead of 100%. On your chart. You have it going from 100,90,80 and so on. Any idea how to convert your chart for an 126% throttle?
Because my throttle is set to display percentage. If you want it to display speed steps then change it in the settings.
@@DBRXCustomRailroadModels ah ok, well I have an Iphone and it looks like I can't change the throttle from speed step to percentage. Using WiThrottle. But thank you.
What is the link to download the spreadsheet?
goo.gl/mW8SHV
Thanks!
Great video! I was going to use the speed table method but will try this first. I did not buy a speedometer, I built one that Joe G shared on his channel. It's Arduino based with a few sensors and a display - very simple to build and use/modify to fit your needs. If interested in the code, send me an email - address is viewable on my channel page - Smokin Big Dave BBQ and Trains
Can we still acquire the spreadsheet?
I figured is formula out just I don't know how to set up an entire spreadsheet like he did but I think you don't need to spreadsheet and just a piece of paper and a calculator. Basically its top speed desired divided by models actual top speed (50/55=90.9%), take that result and divide it by 255 (90.9% or .909/255=231.8) so you'd set it at CV5 max at 232. I hope that helps. Unfortunately the drop box link is dead but this should help you within reason.
@@SPSD458853 Thanks alot!
@@SPSD458853 hoping this finds its way to you. I am going over your math to try and recreate the spreadsheet. I get the first part , 50/55=90.9% but 0.909/255 = .00356471 not 231.8. What am I missing?
DUH!!! Never Mind. It actually is Multiply by not divided by!!!
