My DC trains run fine on track powered by e-z command. However my one and only DCC train for now appears to loose power at certain sections of the track. Not derailing. Suggestions would be appreciated.
If your engine is hitting a dirty section of track rail, that could be the cause.
Try cleaning your tracks and your engine wheels on your DCC engine first (actually the wheels on all engines should be cleaned regularly). DCC engines can be a little less forgiving than DC engines when it comes to drawing power from a track if the wheels or track rails are dirty.
