I have 10th anniversary Polar Express LionChief 1225 steam loco. The chuffing sound works when the engine is idle, but when in motion, it cuts out. I assumed it was the pcb board in the loco so I ordered a new one and when I installed it, the loco idles and the headlight comes but will not move at all. Is there some kind of code you have to send from the remote or something I am missing with the install. When I reinstalled the original pcb, the train works but with the same chuffing problem. Any ideas?
