摘要

A light control system of a railway vehicle is provided to secure a visual field of an engineer at night by controlling the light of an operation room even though a main control key of an operation room is not inserted into a main control key socket. A light(110) is installed in an operation room. One end of a first contact point(120) is connected to the light of the operation room. The other end of the first contact point is connected to a first power source unit(102) to turn on or off the light of the operation room. A first relay turns on or off the first contact point. A second contact point is connected to the first relay and the first power source unit. A second relay turns on or off the second contact point. An operation room selecting switch(150) is connected to the second relay and the first power source unit. The selecting switch is mounted outside the right and left entrance door of the railway vehicle. The operation room selecting switch turns on or off the light of the operation room by turning on the operation room switch outside the operation room.
