THE A.T.C. (AUTOMATIC TRAIN CONTROL) AND A.P.B. (ABSOLUTE PERMISSIVE BLOCKING) SYSTEMS IN AUTOMATIC TRAIN RUNNING

LOS SISTEMAS A.T.C. Y A.P.B. EN LA CONDUCCION AUTOMATICA DE TRENES

A paper read by the author at the Symposium on automatic train running, held in Madrid in March 1975. The author describes in particular the Societe Alsthom's A.P.B. symmetrical signalling system, for which the continuous track circuit serves as a basis. This system offers attractive new possiblities in automatic train running and signalling. He also describes the S.C.A.R. safety system (Systeme de conduite automatique par rapport a la vitesse limite), also developed by the Societe Alsthom for the Lyons Underground.
