Thanks

I have an MTH RK F3 unit that does something very similar. On the rollers, only the tach motor would move until about 6 or 7 SMPH, then the other motor would start to move but slower. On the track by itself the engine would jerk at low speeds until you got it up to about 5 SMPH. It would operate much better when it was under load.
I figured a motor is going out but as long as it was working with a load, I won't do anything with it until another failure warrants the need for a replacement.
