Automatic train stop position control equipment for the site of former expo'70

A reference pattern and control system were examined for specifications given to automatic train stop position control equipment for Japan's Expo'70 site. A constant braking instruction was given after a train passed the final landmark, and the train was proportionally controlled to trace pattern 1 (deceleration 2.8 km/h/s) and pattern 2 (deceleration 1.5 km/h/s). A high-reliability automatic operation control equipment was developed by using magnetically controlled transistor logic elements. Field tests satisfied specifications for controlling action and stopping accuracy. Practicability of the system was proven by operation results for six months.
