CBTC is a signalling standard defined by the IEEE 1474 standard. [1] The original version was introduced in 1999 and updated in 2004. [1] The aim was to create consistency and standardisation between digital railway signalling systems that allow for an increase in train capacity through what the standard defines as high-resolution train location determination.

Transmission-based train control (TBTC) is a communication technology protocol used in railway signaling. [1] It encapsulates all railway signaling methodologies or frameworks that rely on the communication between the control room, trackside systems and onboard systems to ensure safe train movements.
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 ...
Interoperable Communications Based Signaling (ICBS) is an initiative backed by the Federal Railroad Administration to enhance interoperability and signaling procurement in the railway system of the United States by creating a single national standard for train control and command systems. The concept was launched in 2005 and an interoperable ...
The system's rail lines run on eleven lettered "routes". Within these routes, each station is also identified by a letter and number system based on the route letter and the station number in ascending order from the system's geographic center. This is known as the Remote Terminal Unit (RTU) number.
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.
