Visitor Comments about this Photo:
When a train is in the circuit and shunting, a push button on a post on either side is interlocked with the traffic signals. After one of the crew pushes the button, in a few seconds they all turn red and a flashing light then alerts the train crew that all vehicle traffic has a red light.
