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.
According to the IEEE 1474 (1999), communications-based train control (CBTC) is a continuous, automatic train control system utilizing high-resolution train location determination, independent of track circuits and continuous communication between train onboard systems and wayside systems. [6]

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.
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.
CBTC is the most common associated standard, however CBTC as it is described in IEEE 1474 (1999) [7] makes no mention of a requirement for moving block operation. That said, the overwhelming majority of moving block systems use a signalling system consistent with the IEEE 1474 (1999) standard.
[89]: 10 CBTC, as well as the new track configuration added in the line's 2015 extension, allowed the 7 and <7> services to run 2 more tph during peak hours, increasing service from 27 to 29 tph. [90]: 24, 40 [56] A transponder at Mets–Willets Point. CBTC-equipped trains use such fixed transponders to locate themselves.
