TRACK-LOCOMOTIVE TRANSMISSION THROUGH THE RAIL

A paper read by the author at the Symposium on automatic train driving, organised by the AIT in Madrid in March 1975. He describes a permanent track-locomotive data transmission system, based on the use of a track circuit with electrical separation joints. The article also mentions the track-side equipment and the devices aboard the locomotive, also the use of compensating blocks for increasing the range of track circuits on long-distance lines. The SNCF has an already tried out this system and plans to use it on the Paris-Lyons line.
