inspections causing locomotives to be withdrawn from service for lengthy periods, the availability factor would have been much higher as there was practically no serious trouble in any of the locomotives during the year.

37. The maintenance cost of the diesel-electric locomotives rose from $0.366 to $0.440 per km. The increase was mainly attributable to the renewal of wheels for 3 locomotives and to the renewal of cylinder liners of locomotive No. 53.

38. Carriages and Wagons. In addition to routine maintenance, the following items were the more important work done on carriages and wagons:

(a) Carriages Nos. 111, 201, 202, 206, 303, 313, 315, 321, 322, 332,

333 and 334 were overhauled and painted.

(b) Two covered wagons Nos. 45482 and 45483 were converted to

mail wagons.

(c) Eleven wagons were overhauled and painted.

(d) Thirty two wagons were given a general inspection and repair. 39. Work done for other Government Departments. A considerable amount of work was done for other departments of Government. The most important items were the manufacture of 13 hot water cylinders, 100 spalling hammers and 50 bins for refuse hand-carts, the retyring of the rolls of one motor roller, the repair of 91 refuse hand-carts and the machining of 8 cast iron end covers for air-conditioning plants.

Statistics.

(a) The average consumption of diesel fuel for the year under review was 3.13 kgs. per engine km. as against 2.89 kgs. per engine km. for the previous year. The increase in consumption was due to the higher fuel consumption of the 3 more powerful locomotives which were put in service at the end of August 1961.

(b) Coal consumption was 13.45 kgs. per train km. and furnace oil consumption was 11.51 kgs. per train km. Since the mileage operated by the steam locomotives was small, these figures cannot be used as indices for the operating efficiency of the steam locomotives.

(c) Statistical statements relating to analysis of train and locomotive kilometrage, coal and fuel oil running expenses, consumption of lubricants and costs of repair to locomotives, carriages and wagons will be found at Appendices VII to XII while classifica- tions of rolling stock are at Appendices XIII to XVII.
