ADVANCEMENTS IN AUTOMATIC TRAIN CONTROL FOR RAPID TRANSIT SYSTEMS

A versatile and proven solid-state train control system has been operating on the Paris Metro since 1970. An updated version of this system is now being offered in the U.S. Unique features of this system are: track circuits for train detection that have a block detection accuracy better than one foot with continuously-welded rail, and are virtually immune to propulsion return-current harmonics; a highly flexible two-way data link between the trains and the wayside using a remote inductive antenna; and extensive use of lightweight, fail-safe solid-state relays in both wayside and carborne equipment.
