Trevor Moore B Eng, MBA, FIRSE, FIEAust Australian Rail Track Corporation The Concept Signalling Plan is often used to allow scoping and costing of a project for approval at an early phase in a project program. While it is basically a cut down version of a Signal Arrangement Plan, the compromises in producing the Concept Signalling Plan often result in significant differences in the verified final Signal Arrangement Plan. These may lead to variations in scope, rework, cost increases and project delays. The only advantage of the Signal Concept Plan is that it can be produced with only a little effort, as there is still the need to produce the final Signal Arrangement Plan. Considering the disadvantages that can flow from an incorrect signal concept plan, the advantages are vastly overshadowed. Producing the verified Signal Arrangement Plan in lieu of the signal concept plan allows the project to proceed on a firm basis and achieve the required outcomes with the minimum of rework. This paper examines the advantages of designing the Signal Arrangement Plan at an early phase in the project and deleting the requirement for the Concept Signalling Plan.

G Shea Westrail An interactive computing system for the control of pur- chasing for Westrail has recently been established. Supporting communication facilities consisting of main and standby data links, peripheral switching, order wire and multiple line telephone access have been provided by the Signal and Communications Branch.
WJ Adamson AMIRSE In recent years, the importance of a modern, efficient, signalling system for the Railways of Great Britain has increased enormously. Since the Nationalisation of the Railway Companies in 1947, the British Railways, or British Rail, as it is now called, has spent over £400 million on the modernisation of its Railway System, to meet the demand for a faster and more economic service. The signalling system has advanced from being a means of providing safety for the running of the railway, to a point where it is essential for the control of the railway network and although safety is still a basic requirement, the purpose of such a system is to co-ordinate and control1 traffic in the most efficient and economic manner possible. This paper has tried to outline some of the many developments which have taken place over these years of modernisation and to stress a few of the advantages which may be gained from extensive signalling installations.
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
