 DCC (Digital Command Control) is a system that allows you to operate your trains, not your track. [:)] A small electonic device called a decoder is placed in each locomotive and receives digital signals from the Command Station through the rails. Basically, the command station puts out a constant voltage to the rails. A digital signal is superimposed on the AC track voltage to reach the decoder. The decoder will respond only to singals intended for it. -sd80mac-
