My Lionel PRR Camelback (6-18091) runs great, has a great whistle but alas, no chuff. What component(s) are responsible for the "chuff"? Could it be the tether in this engine? It does not have an IR link, just a 4 pin tether similar to Proto 1 MTH. Or, could it possibly be the motherboard? Thoughts?
thanks,
Milt
