DEVICE FOR AUTOMATIC INTERLOCKING WITH TRACK CIRCUITS WITHOUT INSULATED JOINTS Russian patent published in 1998 - IPC

Abstract RU 2116923 C1

FIELD: railway transport. SUBSTANCE: device has track generator and track receivers placed between traffic lights signals. Two track circuits are laid within the limits of each block section. Track circuits are supplied from common generator connected to rail lines in the middle of block section. Front contacts of direction relay repeaters connected between track receivers and rail lines are designed to connect track receivers to rail lines for a distance of track circuit additional shunting zone from intermediate light signal in direction of train running depending on preset direction of movement. EFFECT: simplified design, enhanced reliability. 1 dwg
