A GREEN LIGHT FOR ADVANCED TRAIN CONTROLS

P S Kalra

Abstract

Second generation train control functions include automatic train supervision (ATS) with computers monitoring train location and performance to modify stopping times and running time between stations. Systems developed in the U.S., Britain, France and Germany are described and compared. Transposed cables, moving blocks, centralized computer control and microprocessors are used in various combinations to achieve various levels of sophistication.
