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.
In this paper, we would like to introduce an innovative proposal based on the research conducted by the Hitachi Rail Innovation team to further improve the existing available tablet application, particularly
This Paper investigates the issues regarding use of passive level crossings for livestock movements in the agricultural industry. This unavoidable practice presents a different risk profile to the typical user, with livestock movement being
I started in signalling more than 30 years ago at British Rail, where I learnt how to design interlockings, initially in relay circuits, and then by programming Solid State Interlockings. This work sparked my interest in safety critical syste
The term signalling principles is often referenced with regards to the design of a signalling system. It is also used as part of the title of a person ‘Principles Verifier’ or ‘Principles Tester’. Some rail managers also reference signalling p
This paper offers a detailed FRMCS integrated migration strategy as a preparatory guide for current GSM-R users, particularly Rail Transport Operators (RTOs), as well as for projects in the planning and developmen
The Public Transport Authority of Western Australia (PTA) is currently building a new mobile radio and backhaul transmission communications network across the Perth metropolitan electrified railway network.
Today’s railway fatalities are arguably more likely to occur at level crossings than in the train collisions we tend to focus most attention on controlling. Designing for level crossing safety can be messy and grey, especially when the dependen
The Netherlands is rolling out the European Rail Traffic Management System (ERTMS) across the national network. The government created a Programme Directorate to manage the rollout. Cyber security for both ERTMS as well as the transportation syst
To support the acceptance of safety risk for configuration changes to railways, systems engineering recognises both qualitative and quantitative hazard and risk assessment methods. Quantitative analysis can be perceived as objective and quali
Cybersecurity is a hot topic worldwide with regular attacks being performed against multiple domains.
