I have a MTH PRR S-2 (30-1149-1) that is Proto-Sound equipped. It's a really nice looking locomotive and quite the puller. Well, last night it started acting weird. I have a loop of O48 FasTrack on my living room floor that I run trains on, and the S-2 has been my motive power for the last month or so. I turn it on and let it go round and round. My 1 year old loves it, and I enjoy watching it go as I destress from the day. Well, it just stops, randomly, but the sounds keep going like the locomotive is in motion. If I push the direction button it goes into neutral, and another press and it goes backwards. I wonder if it was binding, so the next time it did it, I got down and pushed the locomotive a bit in either direction. It acted like the motors aren't getting any power. When it stops, the squealing brakes sound and the locomotive rolls to a stop just like if I had cut the power or pressed the direction button on the transformer, but the sound are still going and changing the voltage will increase and decrease the turbine sounds. Has anyone seen this before on a PS-1 locomotive? I'm guessing that the bottom board is going, whatever controls the voltage to the motor is cutting out on it. It doesn't do it if I do lots of direction changes, only if I let it go for a while, when I sit back and watch it go. Is there something I can check or replace on the PCBA?
