NSWGR 3-arm semaphore shunt signal, ShA ShA ShA, lower quadrant, op detect, 22ft post mount

NSWGR 3-arm semaphore shunt signal, ShA ShA ShA, lower quadrant, op detect, 22ft post mount

A lower-quadrant, manually-operated, semaphore signal with 3 vertically-aligned arms mounted on a 22ft post.
The semaphore arms from top to bottom are: 1) Shunt Ahead, diverging left; 2) Shunt Ahead, without diverging; 3) Shunt Ahead, diverging right. All shunts beyond the signal are onto unidirectional track with same direction as the shunt movement or onto bi-directional track.
Each semaphore has a rod linkage to an operating-detection relay switch mounted underneath it. This was used to toggle a lamp mounted in line with the signal-box lever which operated the respective semaphore. Such detection circuits were used when sighting a signal from the signal box was not possible.
For correct automatic operation the signal must be used with directional feathers to uniquely identify the 3 possible paths indicated by each semaphore. Use <kuid2:60850:23911:4> 'Sig T Feather Left 1 (pos 1)' to mark the path of the top semaphore; <kuid2:60850:23901:4> 'Sig T Feather Straight' to mark the path of the middle semaphore; and <kuid2:60850:23921:4> 'Sig T Feather Right 1 (pos 4)' to mark the path of the bottom semaphore.
