Speed sensitive visual warning system for locomotives |
摘要 |
A visual warning system for a locomotive includes a light signal unit mounted on the body of a locomotive which is connected to a control module which provides for both manual and automatic energization of the lights. In the automatic mode, the lights are enabled at or above a predetermined speed and disabled when the locomotive is below the given speed. The light energization works in conjunction with other warning systems, particularly a locomotive horn.
