A replacement GW type 12B box was built here in February 1938 with a 110 lever VT5 frame. Some unusual locking was provided between levers 15 (Up Main Starting) and 17 (Up Main Advanced Starting, slotted by Tramway Junction). A spring lock implemented 17 locks 15 normal (non-recip.) preventing lever 15 being restroked until lever 17 was restored."
