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).
Model Railroader publishes two annual special issues: Great Model Railroads showcases 10-12 spectacular model railroads, including large, inspirational photographs, detailed track plans, and how-to information. Model Railroad Planning deals with aspects of designing and constructing a model railroad. Typical articles focus on reproducing ...
Hornby Railways Zero 1 was a forerunner to the modern digital model railway control system, developed by Hornby in the late 1970s. It was based around the TMS1000 four-bit microprocessor. The Zero 1 system enabled the simultaneous control of up to 16 locomotives and up to 99 accessories such as points and signals.

Also used in Australia to model 2'6" and other narrow gauge prototypes. On3: 1:48: 19 mm O-scale models of 3 ft narrow-gauge prototypes running on 3 ⁄ 4 in (19 mm) gauge track. O16.5: 1:43.5: 16.5 mm British narrow gauge running on HO gauge track. Prototypes of many diverse gauges are depicted in this scale, as well as fictitious lines.
The main disadvantage of three-rail track is its lack of realism. While some real-world trains do use a third rail, the prototypes for the majority of model railroad operations do not. Lionel tried to improve this situation in the late 1950s with its Super O track, which blackened the middle rail and made it thinner to reduce its visibility.
System information modelling (SIM) is the process of modelling complex connected systems. System information models are digital representations of connected systems, such as electrical instrumentation and control, power, and communication systems. The objects modelled in a SIM have a 1:1 relationship with the objects in the physical system.
