I have several Bachmann DCC on Board locomotives (approx. 15 locomotives) that I either acquired through an auction (eBay) or were given. I am using a NCE ProCab R DCC Controller for my layout. I understand from the paperwork that came with the locomotive the default decoder address is "3". I programmed this in the NCE handset. I am unable to have the train respond to it, whether it is to move(forward or reverse) the locomotive or have the lights turn on. At his point I am very frustrated that I am unable to have the trains, regardless of which one I pick, function. Please.
