The DCC protocol is defined by the Digital Command Control Working group of the US National Model Railroad Association (NMRA). The NMRA has trademarked the term DCC [ citation needed ] , so while the term Digital Command Control is sometimes used to describe any digital model railway control system, strictly speaking it refers to NMRA DCC.
Equipped with DCC, locomotives on the same electrical section of track can be independently controlled. While DCC is only one of several alternative systems for digital model train control, it is often misinterpreted to be a generic term for such systems. Several major manufacturers offer DCC systems.
Trainmaster Command (TMCC) is Lionel's electronic control system for O scale 3-rail model trains and toy trains that mainly ran from 1994 to 2006. Conceptually it is similar to Digital Command Control (DCC), the industry's open standard used by HO scale and other 2-rail DC trains.
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).
In 1940, the Rock Island Railroad approached ALCO about building a road switcher locomotive, for both road and switching service. [1] To meet the Rock Island's request, ALCO created the RS-1. Their new design was a hood unit, in contrast to most existing locomotive designs at the time which were predominantly carbody units. The hood unit design ...

Today, Märklin manufactures and markets trains and accessories in Gauge 1, HO scale, and Z scale. In 1994 Märklin acquired the Nuremberg based model train manufacturer Trix producing DC-operated HO and N scale. Märklin's older trains are considered highly collectible, and Märklin's current offerings enjoy premium status among hobbyists.
The RS-2 was a further development of the road switcher concept inaugurated with the RS-1.Externally, the RS-2 bodywork was more rounded. A more significant change was the switch from the RS-1's ALCO 539T engine to the ALCO 244, adding horsepower to better handle heavy road service. [2]
