The semaphore signal on the up platform at Liskeard in Cornwall is this 'gallows' design so that drivers can see it below the canopy of the waiting shelter. The main (higher) arm is the up starter for trains on the main line; the secondary arm (which is 'off' in this view) controls trains moving onto the Looe Branch Line.
