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 ...
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.
The ATS system at the Control Center is not a vital system and serves only to automate the routing of trains based on the overall timetable. The location of the train is also used to inform passengers of arrival times. The MTA's form of CBTC uses a reduced form of the old fixed-block signaling system, requiring that both be maintained at high cost.
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 ...
The BMT Canarsie Line (L service) was the first line to implement the automated technology using Siemens's Trainguard MT CBTC system, as it was a self-contained line with none of the route interlining seen elsewhere around the system. [24] The CBTC project was first proposed in 1994 and approved by the MTA in 1997. [23]
The Toronto subway uses a variety of signalling systems on its lines, consisting of a combination of fixed block signalling and moving block signalling technologies.. The oldest signalling system is known as automatic block signalling and was designed for the system's heavy rail lines: Line 1 Yonge–University, Line 2 Bloor–Danforth and Line 4 Sheppard.
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 ...
The Automatic Train Supervision sub-system provides for headway management and proper interleaving of trains at junctions by speeding up or slowing down trains. [1] The system works via a series of track mounted balises , which function as information beacons transmitting a speed code to the train as it passes overhead.
