P Gobetz-JC-M,H,A. BE (Electronics), BA, MIRSE The final implementation of the Adelaide Yard Resignalling will be undertaken as part of Contract 100. The scope of this contract covers the work in the Adelaide Yard area and extends 2.2 km on the Gawler line and along the quadruple lines to Goodwood, about 6 km from Adelaide Station.Since the original study the developemnt of computerised interlockings had reached the stage where this option was included in the tender.
R. M. WALLACE Co-Ordlnator E Ackninlstrator Non-Urban Radio V/Line. There Is ample evidence to suggest that the danlnant factor affectlng V/Linets current marketperformance is Its perceived Inability to provide consistently reliable service. This has led to the loss of existing freight and passenger traffic as well as lost opportunities to gain sigilficant new business. The timekeeping perfonnance of many malnltne frelght and passenger servlces in relation to the standards laid down normal schedules is clearly far from satisfactory. Experience on other rail systems both locally and overseas, has shown that the selectlve application of radio to train working has the potential to slgnificantly improve this situation on those trains or mutes where operating problems are greatest.
T.S. Howard B.Sc. (Eng.) MIEE, FIRSE, C.Eng. Marketing Manager Westinghouse Signals Limited The notice on the Board announced that a strictly limited number of places were available for a visit to the recently commissioned new power signal box at Waterloo. Fifth and Sixth form boys who were taking science subjects could put their names down to attend. For no more noble reason than that such an expedition promised to be a more diverting occasion than another afternoon spent in compulsory support of the school's ill fated cricket team, one teenage boy at that English boarding school at the end of the last war applied to go on the visit.
Christian Wullems BIT(Hons) PhD MIEEE MACS Cooperative Research Centre for Rail Innovation George Nikandros BE CPEng FIRSE MIEAust MACS (Snr) Australian Safety Critical Systems Association Peter Nelson-Furnell B.Bus(Transport) Public Transport Victoria Low-cost level crossings are often criticised as being unsafe. Does a SIL (safety integrity level) rating make the railway crossing any safer? This paper discusses how a supporting argument might be made for low- cost level crossing warning devices with lower levels of safety integrity and issues such as risk tolerability and derivation of tolerable hazard rates for system-level hazards. As part of the design of such systems according to fail-safe principles, the paper considers the assumptions around the pre-defined safe states of existing warning devices and how human factors issues around such states can give rise to additional hazards.
GRAEME ACKLAND B. App. Sci (Elec) SIGNAL INTERLOCKING ENGINEER PUBLIC TRANSPORT CORPORATION - VICTORIA (THE MET) The Clifton Hill to Epping line was first constructed in December, 1904, and was electrified in stages from 1921 to 1964. The line is about 17km in length, and has very little traffic other than Electric multiple units carrying commuters. When the the re-signalling project was conceived in 1985, the signalling consisted of a section of automatic signalling, dating from 1926; manual Double Line Block from Merri to Keon Park with mechanical operation of points and signals; and Staff and Ticket operation from Keon Park to Epping, with some power operation of points and signals at Lalor. The level crossing protection consisted of four sets of hand gates, three sets of interlocked mechanical gates, and eight sets of boom barriers. A greatly added impetus for the re-signalling of the Epping line came from the decision by the Victorian Government to establish a train Maintenance Depot at Epping and so release valuable central city land at Jolimont. This added and complemented the project by requiring an increased train service and a major interlocking at Epping.
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
