What are the odds of that happening? Glad you tracked down the problem.

As a last ditch effort, you could probably order a pair of 6 pin plug and 7 pin socket harnesses or vice versa from BLI or another source for testing purposes. You would have to figure out which wires go where. Then you could make an adapter harness with a 6 pin plug on one end and a 7 pin socket on the other, or vice versa.

Doug, did you try hooking the faulty locomotive to the tender on the other locomotive that is running well?

Doug, the one thing that stands out to me is the fact that the problem does not occur when the loco is in reverse. That would pretty much eliminate any track or power problems. It would also seem to eliminate the LM2-S having a problem.


I have the same BLI Blue line light Mikado with an LM-3S installed and it runs beautifully. I would say your problem is definitely in the tender or the locomotive connector, putting emphasis on the former.


I'm sure someone else will jump in here with suggestions.

RailPro Discussion & Help / Re: "Incompatible sound file"
« on: February 26, 2020, 02:12:54 PM »
I doubt this would cause that but could there be another large sound file already on the LM-1? Even if there was, you shouldn't be getting that error message. Go to Delete File, select the correct LM-1 loco and see what sound files are on the module. If not, reset the loco by raising one side off the rails.The standard EMD 567 should work.

I know a guy who only runs the same two identical DCC locomotives in consist because they are the only ones that run well together. I have watched guys peck and poke at computer screens for hours trying to adjust CV's. RailPro is nothing like that. The few settings that may need adjusting, as described by Alan, are easy ones to change on the controller, with no computer or CV knowledge needed.

I believe I've found the problem. One of the motor wires was rubbing on a flywheel and a tiny spec of bare wire was evidently touching it. I insulated that spot and now they seem to be running together happily. I'll do some more testing to confirm. Alan, thanks so much for all your good advice.  :)

I'm going to take a good look at all the wiring on that loco. The fact that the problem is intermittent leads me to think that is where the trouble lies. They do have to be physically connected, with or without a car in between, and they have to be facing opposite directions for the overload to occur. When facing the same direction, no problem. Pretty weird.

I put a car between them and set the original problem engine as the lead, running in a forward direction. They ran for at least 5 minutes with no errors. Then I reversed them and after about 2 minutes, as I brought them to a halt the problem loco went to overload. At that point I couldn't get it to run at all. Each time I reset it and barely moved the throttle it overloaded.

I went through several scenarios and have come up with the following:


Either loco runs perfectly by itself in both directions.
They run perfectly when linked, but separated.
They run perfectly when linked and connected and both are going in the same direction.
The problem only occurs when linked, and connected in opposite directions. Then either one or both go over current.
There is no apparent electrical connection between them through the couplers.

I did the fuse test using a 1A fuse. Ran the current up to 16% and it did not blow. Of course, the Over Current error did not come up either.  ???  Other than an intermittent motor wire short I guess there is nothing left to check, though I'm still not understanding why it only happens when they are linked.

General Discussion / Re: Perspective Railpro user has some questions...
« on: February 23, 2020, 08:48:16 AM »
I have Atlas snap switches. I have found that shorting only occurs on the #6 switches and not on #4's, though I can't explain why. It also depends on the locomotive. Older ones with deep flanges and some 6-axle locos seem more prone to shorting while newer engines pass right through. I am going to try grinding the frogs where the opposite rails almost come together as shown in Dave's video below. As mentioned, the RP power supplies do a good job of protecting the LM modules. I have not burned any up so far.

That would work. I'll give it a try.

Alan, I actually have an old 1A fuse, but getting it to stay between the couplers is impossible. I think the fastest and easiest solution, since these two locos always run in consist, is to change the couplers and see what happens. Now the question is: "Do I still have any plastic couplers"?  :D

I'll try the fuse later and report back. I appreciate the help.
