Improvements to Optical Information Transmission System Based on Light Rail Train

摘要

A light transmission system for a train which includes sub-train compositions. Ths subtrain compositions each have end vehicles, one of which forms a head and the other of which forms a tail with respect to the moving direction of the train. The end vehicles each include a central station responsive to a first command signal from the front platform of the train to perform a central function for producing a second command signal and responsive to the second command signal to perform a terminal function which passes therethrough any input signal when an adjacent central station is found to be connected thereto and which returns any input signal when no adjacent central station is found to be connected thereto, thereby forming a complete signal transmission path in the train.
