WAYSIDE-TRAIN RADIO OF THE FRENCH NATIONAL RAILWAYS

LES LIAISONS RADIO AVEC LES TRAINS A LA S.N.C.F.

The system described was designed to enable two-way radio telephone conversations to be made between the drivers of trains in motion on the one hand and traffic controllers, sub-station supervisors and staff at certain stations on the other, as well as between the drivers of trains in the same radio section. The equipment also enables a driver to set off a "radio warning" if there is an immediate danger to traffic. An alarm signal is received by the traffic controller if a train is stopped by the automatic vigilance device. The article explains how the system functions and its advantages, particularly as regards safety and the free flow of traffic. It contains a technical description of the equipment and its operation.
