Hi I have a o gauge New York Central line MTH train. I have had this unit about five years and now the sound and smoke are working intermittently. The thing is that they work at the same spot on the track as they go around. There are about six places on the track that they will kick on for a second and then shut off. Im guessing I have a track problem but do not know how to correct it. Has anyone ever encountered this problem.
