I believe this is called a Two Position Upper Quadrant Semaphore Signal. 1) Horizontal arm: Means "Danger" (Stop). At night, a red light is shown. 2) Arm inclined upwards at 45 degrees: Means "Off" (Proceed). At night, a green light is shown. The beauty of this system is that in the event of a signal control wire failure the signal arm will just drop down to the horizontal ‘stop’ position due to the simple effect of gravity. This one is on the Great Central Railway in Leicestershire. Some other
