AUTOMATION AND SAFETY OPERATION OF METROPOLITAN RAILWAYS BASED ON HIGH-TENSION IMPULSE TRACK CIRCUITS

This article describes the train control system developed by Jeumon-Schneider that is being installed on the Montreal and Marseille Metros. There are a number of self-contained functional elements which may be applied separately, or combined to integrate their several functions. The functions are high-voltage impluse track circuits, train- to-train communication or cab signals, continuous speed control; driverless train operation, and section-timing control of train operations. Application of linked self-contained modules avoids total failure and running may continue under proper manual operation.
