type equipped with an electric lock, circuit controller and two key locks, and is interlocked with the signal levers in the frame so that the control lever will release the appropriate signals and also enable the proper key to be extracted and inserted in the block instruments. The keys for operating the block instru- ments at Fanling and Wo Hop Shek Stations are transmitted by two pairs of Hepper's Electric Key Transmitters.
All signal arms, point indicators and fouling points were also cleaned and painted during the year.
32. Tunnels and Bridges. All tunnels and bridges were found in good condition and very little repair work has been carried out during the year.
33. Cuttings and Embankments. There were no major landslips nor wash-outs. Only minor repairs to the old face plasters in some cuttings were carried out.
Dangerous cracks developed in a portion of rock cutting 130 ft. in depth at Mile 13. About 500 cubic yards of dangerous rocks were taken down by blasting and all overhang- ing or loose boulders were supported by cement concrete walls for the protection of this deep cutting.
34. Drainage. Every opportunity was taken to improve the drainage along the main line and on top of the high cuttings where necessary as funds permitted during the year in order to prevent major landslips or wash-outs.
New drains were also constructed on the sides of No. 4 Road at Yaumati station yard to carry away the accumulated dirty water from pig wagons into underground drains so as to leave the track in a clean and sanitary condition.
35. Fencing. 1,325 yards of new galvanized iron chain- link wire netting fence were erected at Shatin Station to protect loss of revenue and to prevent pedestrians from crossing at this busy. station.
Yaumati station yard was also enclosed with old iron pale fence to keep out trespassers.
