The efficient and economic operation of the system depends on adequate, well laid-out depots with the necessary facilities. These aspects have been investigated in detail and layouts prepared. The control centre, administrative H. Q. and principal maintenance depot for the system would be at Kwun Tong, but each line would have its own sub-depot.
COST OF CONSTRUCTION
