Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems. This can make railway traffic management safer and more ...
CITYFLO 650 CBTC system CITYFLO 650 signalling is a CBTC system designed by Bombardier Transportation and later Alstom . It makes use of bi-directional radio communication between trains and wayside equipment, as well as true moving block technology, to control train operation.
Trainguard MT is a communication-based train control (CBTC) developed by Siemens Transportation Systems (ex Matra Transport international, and now integrated into Siemens Mobility) which allows fully automated circulation of rapid transit trains, and thanks to moving block system, less time between trains.
In railway signalling, a moving block is a signalling block system where the blocks are defined in real time by computers as safe zones around each train. This requires both knowledge of the exact location and speed of all trains at any given time, and continual communication between the central signalling system and the train's cab signalling ...
Positive Train control is a type of automatic train protection system that prevents train-to-train collision, over speeding and unauthorized train movements. [4] It used GPS technology and wireless radio to calculate safe distances between trains to transmit movement authority from the onboard controllers on the following train, to the wayside ...
Headway is the distance or duration between vehicles in a transit system. The minimum headway is the shortest such distance or time achievable by a system without a reduction in the speed of vehicles. The precise definition varies depending on the application, but it is most commonly measured as the distance from the tip (front end) of one ...
