Digital Command Control (DCC) is a scheme for controlling locomotives on a model railroad layout. It allows more than one locomotive to occupy the same electrical section of track.
The most basic Digital Command Control (DCC) system consists of several parts: a throttle, a command station, a booster, a decoder, and a power supply to run it all. Most systems also use a throttle network which allows multiple throttles to talk to the command station.
