Digital Command Control (DCC) is a standard for a system for the digital operation of model railways that permits locomotives on the same electrical section of track to be independently controlled. The DCC protocol is defined by the Digital Command Control Working group of the US National Model Railroad Association (NMRA).
The system was originally referred to as the Hapsburg Carrier System. DCC was not implemented in transmitter designs until the 1980s, because of some of the complexities of the control circuit. DCC's development is linked to NATO nations trying to save energy as a result of the ripple effects of OPEC related oil supply crises.
Zero 1 was based on digital, not analogue, technology. This really was the first digital system [4] and as such was a forerunner to the Märklin Digital which appeared in the mid-1980s and the National Model Railroad Association (NMRA) Digital Command Control (DCC) system, which appeared around 1990 and was standardized internationally in the ...

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.

Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
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).
Parallel running is a strategy for system changeover where a new system slowly assumes the roles of the older system while both systems operate simultaneously. [ 1 ] [ 2 ] This conversion takes place as the technology of the old system is outdated so a new system is needed to be installed to replace the old one. [ 3 ]
