DCC Products

DCC - digital command control - is a control system for the model railway where a decoder onboard the locomotive is used to provide control of speed and direction of the motor. The instructions are passed from the 'throttle' to the decoder by means of digital signals that are superimposed over a constant track voltage. Put simply, you control the locomotive and not the track. As well as output to power the motor, many decoders also have a number of auxiliary outputs that can power other functions: lights or smoke for example, and really fancy decoders also have sound. As there is always voltage at the track these functions are not related to train speed as happens with lights on direct current (DC) controlled trains. There are also decoders that will power stationary operations - points, signals, etc. - all from the same handset as you run your locomotive.
