Definitions

A train protection device that automatically stops a train if it attempts to pass a signal when the signal aspect and operating rules prohibit such movement, or (in some applications) if it attempts to pass at an excessive speed.

Examples

“In the simpler operating conditions of the London Transport lines, plain automatic train stops, applying the brake if a red indication is passed, give all that is required. With improvements in design, they have been in use over half-a-century.”
