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

It permits operation of multiple MTH ProtoSound 2.0 (PS2.0) engines 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. While MTH's DCS will not operate TMCC locomotives directly and Lionel's TMCC will not unlock all the control features of PS2.0 engines, the two systems will easily operate side by side on the same track. Therefore engines with either system can be operated simultaneously as long as both command control units are installed on the track.
