JR Moore BSc, BE, AMIE Aust AMIEE Resident Engineer (NSW) McKenzie & Holland (Australia) The latest review published in the Proceedings of the Institution of Electrical Engineers, U.K,, indicates that conversion to direct current by means of rectifiers accounts for something like 30% of all the electrical energy generated in the world: and like the latter,it is approximately doubling in volume every ten years.

DE McCauley MIRSE In this paper I intend to outline very briefly the history of Level Crossing Protection in Victoria and to describe some of the control problems and principal technical features of the design of flashing light signals and half-boom barriers with flashing light signals (later reffed to as boom barriers). Legislation in the United Kingdom requires the Railways to protect the road user at rail-road level crossings.  In the United States of America legislation requires the road user not to cross the rail unless he can do so safely. In Victoria, the Birtish practice of protecting level crossings was used in cities nd towns.  Today, of the crossings in the Melbourne Suburban Electrified Area, approximately 200 are portected and only about ten are not protected.

WH Dawkins Westrail The Forrestfield yard, opened in 1973 centralises the marshalling of loadings for country designations previously performed at Midland, East Perth, Perth and Fremantle yards. It is divided down the centre with standard gauge on the east and narrow gauge on the west. A description is provided of the narrow gauge 'hump"marshalling yard. A total of 7,449 Dowty Oleo retarders are installed over 31 classification sidings for continuous speed control of wagons and buffing speed. Information is provided on the operation of these retarders and on the major aspects of the yard including the control tower, operating console, hump signals, shunt signals, points,track circuits, the automatic route progression system, test panel and the compressed air distribution. A full description is provided on humping and operating procedures.

A.A. Carey This paper describes the review carried out by the S & C Department to establish a criteria to rehabilitate the Metropolitan signalling system to a defined standard of signalling to ensure the continuing safety of passengers, improved operating efficiency and maintainability of systems. The train running capacity of each signalling systemhas been determined and the systems to be rehabilitated have ,ben identified. The Operations Department is to review their train running requirements as they relate to main line signalling and also the impact of the stabling decentralisation.
