21Digital Command Control — For other uses, see DCC (disambiguation). Digital Command Control (DCC) is a standard for a system to operate model railways digitally. When equipped with Digital Command Control, locomotives on the same electrical section of track can be… …
22Continuous Automatic Warning System — For the gun, see Heckler Koch HK CAWS. For the wrestling video game creation mode, see Create a wrestler. The Continuous Automatic Warning System (CAWS) is a form of cab signalling and train protection system used in Ireland to help train drivers …
23Vector control (motor) — Vector control (also called Field Oriented Control, FOC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three phase AC electric motors by controlling the current fed to the machine.MethodThe… …
24Digital model railway control systems — A number of control systems are available to operate locomotives on model railways. The earlier traditional analog systems where the speed and the direction of a train is controlled by adjusting the voltage on the track are still popular while… …

26Anti-lock braking system — An anti lock braking system (ABS, from German: Antiblockiersystem) is a safety system that allows the wheels on a motor vehicle to continue interacting tractively with the road surface as directed by driver steering inputs while braking,… …
27Airborne Early Warning and Control — An Airborne Early Warning (AEW) system is a radar system carried by an aircraft which is designed to detect other aircraft. Used at a high altitude, the radars allow the operators to distinguish between friendly and hostile aircraft hundreds of… …
28Centralized traffic control — (CTC) is a signalling system used by railroads. The system consists of a centralized train dispatcher s office that controls railroad switches in the CTC territory and the signals that railroad engineers must obey in order to keep the traffic… …
29Automatic Train Control — Japanese style ATC indicator. Automatic Train Control (ATC) is a train protection system for railways, ensuring the safe and smooth operation of trains on ATC enabled lines. Its main advantages include making possible the use of cab signalling… …
30Digital control — is a branch of control theory that uses digital computers to act as system controllers. Depending on the requirements, a digital control system can take the form of a microcontroller to an ASIC to a standard desktop computer. Since a digital… …
