7.21. Close co-ordination was maintained with the Roads Office in the installation of traffic-light control systems and traffic aids. Among the installations completed were two sets of fixed-time traffic-light control systems, one vehicle-actuated traffic-light control system, one set of manually operated railway-crossing traffic-light control signals, 148 new and repositioned illuminated traffic bollards, 38 Belisha beacons, 6 'Cross Here' signs, and 17 illuminated traffic signs. In addition, 9 sets of existing light-control systems were modified to cope with changing traffic demands.
7.22. Other works of considerable diversity completed and put into commission included 10 perimeter lighting installations, lighting systems for 8 bus shelters, 6 emergency generator units, 5 electric hoists, and 6 navigation light installations.
7.23. A low-voltage supply system for use in conjunction with power tools was installed at the Yau Ma Tei Government Slipway.
(B) Mechanical Section
7.24. The Mechanical Section was responsible for vehicles of all types ranging from motor scooters to armoured cars, plant from 40-ton boilers to lawn mowers and items of general equipment from parking meters to passenger-ferry-pier lifts and ramps. During the year, 72,151 orders were completed by the mechanical workshops representing an increase of 12% over the previous year.
Vehicles
7.25. The total number of Government vehicles in service and being maintained by the vehicle section at 31st March, 1964, was 1,868—an increase of 5% over the previous year. The servicing, repair and overhaul of these vehicles left little labour spare for new work and consequently most of the new vehicle body construction was done by local contract. Modifications were however made to a number of vehicles including the conversion of two 15-cwt. open trailers into mobile electrical generator units. One of the Airport Water Tenders was converted into a Foam Tender and an outside-broadcasting van with Radio Hong Kong was extensively modified and fitted with a commentator's platform on the roof.
