#REDIRECT [[Digital model railway control systems#Digital Command System]]
'''Digital Command System''' (DCS) is an electronic control system for [[O scale]] 3-rail [[model railroad|model trains]] and [[toy train]]s, developed by [[MTH Electric Trains]] as a rival to [[Lionel, LLC|Lionel]]'s [[Trainmaster Command Control]]. It is similar in concept to [[DCC]], the open industry standard used by [[HO scale]] and other 2-rail [[direct current]] trains.

It permits operation of multiple trains on the same track without complex wiring, and also gives locomotives realistic digitized sounds.

Unlike Lionel, MTH has not licensed its standard to any other company. Hobbyists often have difficulty getting DCS-equipped locomotives to operate in conjunction with TMCC-equipped locomotives.
