I have two Bachmann GP-50 engines that I want to put DCC into. I have looked at many websites but have not found a place that says what will fit Bachmann engines. I also have a Bachmann Class J 611 steam engine that I want to put a DCC chip into. I want a chip with 4 or 5 functions for lights and stuff. I probably be using a Atlas Master Commander as my contoller. Haven't bought that yet.
