Light transmission system for trains
First Claim
1. A light transmission system for a train including at least two sub-train compositions each composed of a plurality of interconnected vehicles including end vehicles comprisinga command signal generating means disposed in each of said end vehicles, said means in a selected one of said end vehicles used as a head vehicle for generating a first command signal;
- andcentral stations including at least one last central station respectively disposed in each of said end vehicles, each of said central stations including means for receiving operating signals and being responsive to said first command signal for generating a second command signal and responsive to a received second command signal for passing therethrough any of said operating signals input thereto when said central station is a station other than said at least one last central station and for returning any of said operating signals input thereto when said central station is said at least one last central station.

Abstract
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.
