Mark Felstead Austrac Project Team The title for this talk is some what misleading. The parrot is in fact a hand puppet and the frog is an oven glove.These are used to indicate which of the VAX computer backup tapes are the most current. The daily activity of stuffing the parrot and the irregular activity of croaking the frog form a small, but important part, of the Independent Validation and Verification (N&V) task that AN will perform. THE INDEPENDENT VALIDATION & VERIFICATION TASK. The task is to demonstrate (through the combined use of computer tools and human skills) that the software that will control the running of trains on the TAR and part of the CAR is correct ( ie bug free).
G LeClercq Westrail The scope of the South West project was, in order of importance, to provide communications circuits for:- the signalling train control systems based at Picton: Picton to Coolup and Picton to Collie. the emergency telephones installed along the tracks and at the road crossings. Those circuits are all connected to the controller at Picton. the station masters to Picton Control (direct link). the connection of the controllers at Midland and Picton (direct link) the 2 VHF radio bases at Picton and Collie (later Cookernup) PAX phones installed as extensions on Bunbury and Collie exchanges. The existing overhead bearers in the area were inadequate to fulfil the new conmunications requirements and needed extensive upgrading. A cost study showed that, in the long term, a cable carrier system would be the most economical solution, and, furthermore would provide the base for a future upgrading of our communications network between Perth and Bunbury.
Jon RD Pratten BSc BE Divisional Manager, GEC Digital, GEC Australia Limited This paper covers the passenger information display system at Sydney Terminal (Central) Station. The system was provided by the Digital division of GEC Australia Limited under a contract with the State Rail Authority of New South Wales. The system provides television monitor displays of train arrival and departure information for the public at various locations around the station complex. Displays are grouped according to the type of information they present and consist of: 15 platform displays (one per platform) each summarising on one monitor the service information of the train currently a1located to the platform. 10 concourse displays, each split into upper and lower portions on separate monitors and fully describing one of the next 10 departures. 2 sumnary displays, summarising separately the next 10 departures and the next 10 arrivals, repeated on a total of 8 monitors at appropriate locations around the station.
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.
