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).
Accelerate-by-wire or throttle-by-wire, [17] more commonly known as electronic throttle control, is a system that actuates vehicle propulsion without any mechanical connections, such as cables, from the accelerator pedal to the throttle valve of the engine or other propulsion systems. In electric vehicles, this system controls the electric ...
Many ESC systems have an override switch so the driver can disable ESC, which may be used on loose surfaces such as mud or sand, or if using a small spare tire, which could interfere with the sensors. Some systems also offer an additional mode with raised thresholds, so that a driver can utilize the limits of their vehicle's grip with less ...

Of the several competing systems, the command system offered by the majority of manufacturers in 2020 was a variant of Digital Command Control (DCC). The advantages of DCC are that track voltage is constant (usually in the range of 20 volts AC) and the command throttle sends a signal to small circuit cards, or decoders, hidden inside the piece ...
Vehicular communication systems are computer networks in which vehicles and roadside units are the communicating nodes, providing each other with information, such as safety warnings and traffic information. They can be effective in avoiding accidents and traffic congestion.
The most popular digital control systems used in TT scale model railways is NMRA-DCC, most commonly using systems from Roco, Uhlenbrock, Kuehn, Piko or Tillig. There are several coupler systems used in TT. Rokal and Zeuke had simple hook-and-ring systems for their model, but these are rarely used anymore.
A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures.
