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.
Luke King The increasing trend in the complexity of systems poses challenges to project delivery. The use of Systems Engineering (SE) in general, and the use of Model Based Systems Engineering (MBSE) in particular, provides useful techniques in the successful delivery of ETCS L2 signalling projects.
Alex McGrath and Karl Tivan Like many long-lived railways, V/Line works with a collection of inherited, evolved and entangled legacy communications equipment. Starting in 2009, the Regional Rail Link (RRL) project cleaned up a substantial section of the TCP/IP network, providing a core and distribution data network architecture for the central area and two corridors – appropriate for the era.
Trevor Moore The type approval of signalling equipment has been a common practice for over 50 years. Each railway organisation has been conducting the type approval assessments to demonstrate that the new and modified equipment meets their operating requirements.
Paul Szacsvay Dr William Robinson (1841 – 1921) named by the Signal Section of the American Railway Association to be ‘the father of automatic block signalling”, is without doubt the most important unknown ‘hero’ of modern day railway signalling.
Jeanette Aitken Significant value can be gained from making mistakes in a supportive training environment, focusing on feedback and reflection. We look at how different mindsets can shape the response to error and how a fear of failure can impede learning. “Mistakes are a fact of life. It is the response to error that counts”. Nikki Giovanni
Richard Stephens Part of achieving a safe and efficient railway is the competence and capability of those who design, construct, test and maintain the railway control systems. The Institution of Railway Signal Engineers Australasian Section (IRSEA) Graduate Diploma of Railway Signalling is intended to contribute to this.
Aaron Fraser This paper examines the benefits of integrating operational control systems and functions into a single platform, providing a fully integrated user interface to enable operational improvements and a better experience for rail customers.
Stewart Rendell This paper aims to explore some of the technology options that are available now – considering pros and cons of each, and, looks to challenge the more traditional thinking that still exists when it comes to Type Approval of such solutions.
Steven Boldeman & Richard Mifsud This paper reviews and discusses the differences and similarities between these two processes.
Shaun Kindleysides This paper provides a background and overview of the NTCS, outlines the key technologies that underpin the NTCS and describes the complexities, logistics, governance and decision-making principles that are driving the team toward a full deployment of 4GX communications by June 2024 via the NTCS Technology Refresh Project.
