AUCKLAND MUNICIPAL HANDBOOK
The high tension cables which supply the sub-station are lead covered and armoured. They are partly drawn into conduits and partly laid solid in bitumen-filled earthenware troughs.
CONTROL AT JUNCTIONS.
At the corner of Queen and Wellesley Streets a signal tower was erected, in 1916, from which all track points and semaphores at this 4-way junction are electrically controlled. At all other junctions, eleven in all, the track points are electrically operated by means of contactors on the trolley wires, and to enable trolley wheels to follow the right course, boom frogs, operated by the car trolley poles, are installed in the overhead wires.
TOWER WAGGONS.
Three motor tower waggons are in daily use for the examination, repair and renewal of the overhead wires and fittings. The Depôt in connection with this department is situated at Newton Road, near the top of Symonds Street. An emergency man is always on duty here, and, on account of the central position, he can reach the scene of a breakdown in the shortest of time.
CAR SHEDS.
There are two sheds for the depôting of cars, one situated at Jervois Road, Herne Bay, and the other at Manukau Road, Epsom. The tracks in the car sheds
