My Walthers Mainline HO scale SD70ACe with DCC and sound is having problems running smoothly on my layout. I have another GP40-2 DCC engine which runs perfectly, and in this one I installed the DCC chip, no sound.
The SD70ACe has problems at certain points and intervals on my layout, although it has nothing to do with electrical connection between the track and wheels. When it runs over certain points, it will stop moving.
Are there any at-home solutions to this?
