New South Wales Government Railways ground shunt signal. The dwarf, lower-quadrant semaphore arm is hinged to enable recovery from hitting by a passing train. The signal is mechanically operated by a signal wire pulling to the front of the signal.
The semaphore permits shunting ahead onto a track with the same running direction as the shunting movement. If not all paths beyond the signal are covered by it, then mark covered paths with trackside asset 'Sig T Feather Straight',<kuid:60850:23901> and rejected paths with <kuid2:60850:23902:4> 'Sig T Danger'.
