Some digital control systems provide the ability to independently control all aspects of operating a model railway using a minimum of wiring, the rails themselves can be the only wiring required. Other systems are wireless. Control is achieved by sending a digital signal as well as power down the rails or wirelessly.
Conceptually it is similar to Digital Command Control (DCC), the industry's open standard used by HO scale and other 2-rail DC trains. It has one advantage over DCC, in that TMCC-equipped locomotives can run simultaneously with non-TMCC locomotives and Lionel Legacy engines as well as LionChief and LionChief Plus equipped locomotives.

Märklin Digital was among the earlier digital model railway control systems. It was a comprehensive system including locomotive decoders (based on a Motorola chip ), central control (Märklin 6020/6021), a computer interface (Märklin 6050), turnout decoders (Märklin 6083), digital relays (Märklin 6084) and feedback modules (Märklin s88/6088).
Digital control theory is the technique to design strategies in discrete time, (and/or) quantized amplitude (and/or) in (binary) coded form to be implemented in computer systems (microcontrollers, microprocessors) that will control the analog (continuous in time and amplitude) dynamics of analog systems.
CT2 is a digital FDMA system that uses time-division duplexing technology to share carrier frequencies between handsets and base stations. Features [1] [2] [3] of the system are: Standardized on 864–868 MHz; 500 frames/second (alternately base station and handset) 100 kHz carriers; 32 kbit/s ADPCM voice channel compression; 10 mW maximum ...

A modern digital test controller. Digital test controllers are devices (usually computer based) that provide motion control [1] by processing digital signals. Typically a controller has inputs connected to sensors on the device they control, which measure the feedback, its current state (for example the current position), and process this signal to provide an output to a hydraulical ...
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance.
