Speed Matching Locomotives for MU and Distributed Power Consists

In this video, I show you how to program multiple unit consists on a Digitrax DCC system as well as how to program CVs to make locomotives behave more realistically on mountain grades with heavy trains that use DPUs.
Primary load compensation CVs
Digitrax: CV57 - Values between 0-15
ESU: CV54 - Values between 0-255
Soundtraxx: CV212 - Values between 0-255
***For more detailed instructions and supporting CVs, I encourage you to review the manual specific to the decoder being worked on.

You are a natural teacher, clear, thorough and interesting. This is the first time I've seen this explained and you make it sound easy, I didn't even know about load compensation.

That's one of the best and simplest explanations of load compensation I've seen. Thank you very much. I think I'll give it a try now. And i meant to compliment you on the snow sheds in a previous video. They are very good.

Thank you so much for showing this. Im not much of a tech person, and i dont have the equipment some of these guys have. Ive seen too many videos that advertise "the easy way to speed match" and it's all set up with Arduinos, laptops, and speed sensors and all this fancy crap. It's nice to see it possible with just a regular controller. Btw... That's a HELL of a train, and that Montana Rail Link is HOT!!!!

Best one I have watched. That resistance CV has never been mentioned in other ones and makes a lot of sense. Curious your experience with matching different brands of locomotives and decoder’s. I’m having trouble between the scale trains and Athearn. For you or others, if one is engine is still faster than the other do you adjust both CV5 and CV6 or just one?

@railfan220 9 ай бұрын

Thanks! I don't have too much trouble speed matching between manufacturers. Honestly, the biggest trouble I've had is between ESU products. The V5 sound and non-sound decoders have load compensation that is adjustable. But, despite the CVs being listed in the manual, earlier versions of ESU decoders don't seem to be affected when you turn down load compensation. Generally, I'll just adjust CV 6 to find tune speeds between locomotives. I find that I'm usually not running the trains at full throttle even after the top speed adjustments I make, so moving the mid-point voltage (CV 6) up or down has the greatest influence on speed matching. Of course, if the top speeds seem WAY off between two locomotives after an initial round of programming, I'll change it too. But it's usually not that drastic. -Cam

Good informative video but I wonder when DCC will get to the point where its just push one button and go. The RailPro system by Ring Engineering is cool. I guess to much is invested in DCC until the radio control patents expires.

@dennisbailey6067 7 ай бұрын

The original Tsunami doesnt use CVs 5&6.And some brands may not use these in future.So using speed tables,CVs 66&95 can be used to adjust overall speed.But im not sure this is the answer for speed matching.

@jurgendietrichkeit2506 9 ай бұрын

This is good stuff, especially on the BEMF settings. Why is it, though that you are deviating from common practice that says with regards to CV2 that a loco should start crawling on speed step 1? Also: are you programming your locomotives "cold", this is without running them for a few minutes before setting the values?

@railfan220 9 ай бұрын

Thanks! I generally do try to set CV2 so that it starts at speed step 1. It wasn't obvious that was the case in this video. But of course, once the locomotive has some load behind it, it will take more than speed step 1 to get moving. And in the case of these two locomotives, I did do a bit of running beforehand, but I generally don't break them in for too long. I bet it would be beneficial, yeah? -Cam

@samfirn495 6 ай бұрын

Have you ever ran into a decoder? Where the CV Valu foods for the speed table are all 0. But the locomotive still runs normal?

@mikeshorna3355 9 ай бұрын

Thanks for the info, I appreciate it. What values are you using for accel and decel? And do you adjust them as well?

@railfan220 9 ай бұрын

Thanks! I've messed around with using momentum before, but currently don't use it systematically. So if a locomotive comes from the factory with a fair bit of momentum, I'll set CV3 and CV4 to 0 or 1. Some decoders allow button-activated momentum, which is something that I would like to experiment with. But I'd probably only do that if I had decoders that were all the same type. There's too much variability in how momentum is defined from decoder to decoder for me to figure out. -Cam

Hey man thanks for this video. What you did makes a lot of sense and seems to work out. Did you do anything specific to match up your scaletrains engines? I've recently stepped into the world of playing with CVs and now speed matching. For the life of me I cannot understand why I can't get any of my st engines even close. I've tried: using the speed table on JMRI; I've tried using the start, mid, and high CVs; I even tried the forced straight linear speed table line, I turned bemf off, trims, accel/decel off; I spent nearly an entire day on just speed matching 4 different esu ST engines, and at the end I just had to walk away. Nothing I did worked, I watch many videos on what people have done and everything I copied either my engines wouldn't move till like speed step 25 or at speed step 1 moved way too fast. One thing I noticed was that when using the speed table on jmri speed steps 1 & 28 are locked/grayed out and cannot be moved.

@norbertdx 9 ай бұрын

just curious, what's the longest train you've run?

@railfan220 9 ай бұрын

I don't remember the exact number...but I think I've probably run something like a 60-70 car train before? That was a while ago, and I think I put all of the cars I owned into 1 train. But for operations, my trains are usually around 25 cars long. -Cam

How did you get your athearn genesis sd70 to have the dpu lighting setup similar to how scale trains has it?

@railfan220 9 ай бұрын

I basically just set the headlight and rear headlight to be controlled by two separate functions and then enabled them to be on in either direction. I decided to set the rear light to be controlled by F9. Here are the CVs I changed to do that: - set CV31 to a value of 16 - set CV32 to a value of 2 - set CV278 to a value of 255 - set CV258 to a value of 9 Finally, you have to make sure that both headlights are capable of staying on when the locomotive is traveling in either direction. To do this: - set CV57 to a value of 3 - set CV58 to a value of 3 The information pertinent to the changes I made can be found in the Tsunami 2 manual on pages 28, 31, 55, and 56. Here's a link to that manual: soundtraxx.com/content/Reference/Manuals/Tsunami2/tsu2_diesel_usersguide.pdf Hope that helps! -Cam

@@railfan220 Cam, thats cool. I have only ever seen people do this via advanced consisting in JMRI. Thanks for sharing. I like the scale trains DPU headlight settings for longer haul trains, but during operations, it can be annoying to jump between the rear and front locos to get the headlights reset for changing directions. Ill have to dig into this! Thanks!
