ATA RAIL TRANSIT CONFERENCE HELD IN SAN FRANCISCO, CALIFORNIA ON APRIL 14 AND 16, 1974. POWER AND SIGNALS SESSIONS

Three of the papers relate to power and train control systems for rail rapid transit and Pastor describes the state of the art of automatic train control systems. Engle's paper refers to the environmental problems relative to electronic equipment. The Ledsham paper relates to Thyristor Chopper train controls with regenerative power capability and the Toronto test program with this equipment. The Mombach paper discusses NYCTA study of the relative ability of four different types of subway signal cable to function during a fire and the relative toxicity of their combustion products. Mr. Kalkhof studies the cross bonding of running rails to improve the negative return path for propulsion current, and to minimize electrolysis to adjacent structures.
