For more information, I have now attached a 5 amp booster and it is still tripping with 4-8-2 alone and no sound and light off. It is servicing a 2 oval layout that are joined by 2 DCC No6 crossovers. All the track is bachmann track. It can tend to stop at the same point. The stop sign appears on the remote screen and I press and off it goes again. Sometimes it will trip every time around and other times it will go for an hour, half an hour or more and not trip. Any suggestions?
