The subsystems are: automatic train protection, automatic train supervision, and automatic train operation. This article presents information on these subsystems, and includes block diagrams and illustrative diagrams. Train Detection, Automatic Speed Commands, Metro-Link Hardware, Flyby Receivers and Transmitters, and the Door Operating system are discussed.
