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.

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.
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]

Thales Rail Signalling Solutions was a division of Thales Group that supplies transportation-based automation solutions [buzzword] for railways. Its operations are controlled from several locations: its head office in Paris, France; its railway business divisional centers in Ditzingen and Berlin, Germany; Vienna, Austria; and Hengelo, the ...
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.
An example of headway on a railway system with multiple block section. Train B can only enter a section with a green or yellow "aspect" (light), and must reduce speed when passing a yellow signal to the point where they can stop within the sighting distance. Train movements in most rail systems are tightly controlled by railway signalling ...
