Francesco Rispoli Ansaldo STS, A Hitachi Group Company After relatively long periods of operation, the rise of satellite technology and the importance of its great benefits have atlast been recognised as strategic advancements for the train control system business case especially when operationsare in rural and desert areas. The catalysts are a gained confidence in the reliability of satellite technologies and theunprecedented plans to put into orbit new satellites during the coming years. Furthermore, after decades of steadyinnovation in the telecom networks, 5G offers the ultimate solution with millisecond latencies and “network slicing”capabilities to realize bespoke virtual networks. For these reasons satellite technologies and IP-based communicationsare “game changer innovations” for the ERTMS. This paper aims to assess the satellite technology trends, the AnsaldoSTS projects that in Australia have set the world’s bench mark as the early adopter of satellite technology on heavy haullines, and the roadmap to exploit new satellite innovations after the positive field tests in Italy. This plan backed by RFI(Italian Railways Infrastructure operator) aims to contribute to the certification process to implement by 2020 an ERTMSinnovative solution for regional networks based on virtualization of balises through satellite localization, an augmentationnetwork, and the upgrade of the communication system from GSM-R to a public telecommunications network.

Trevor Moore Signals Standards Engineer, Australian Rail Track Corporation The first track circuits were developed in the 1870s. These were used on US Railroads. Over the following years theywere used on railways around the world. There have been substantial developments in the engineering and technologyused in track circuits through to the present time. However, after one hundred and forty five years we are still havingproblems with reliable operation of the track circuits in some applications.This paper will examine the type of trains, track circuit configurations and infrastructure conditions that contribute to theperformance limitations of the track circuit. The paper will cover engineering solutions and recent testing to address thereliable performance of the track circuits.The issue is complicated and involves the signalling equipment, rollingstock and the track infrastructure. Anunderstanding of these issues will assist the signal engineer in addressing solutions for reliable operation.
Alex McGrath Level Crossing Removal Authority (LXRA) The field of resilience engineering explores the mismatch between a system-as-designed, and the actual system as itoperates in the real world, in the presence of shocks, stresses and resource constraints. In signalling systems, themodelling of component availabilities into system availability leads to the belief that more redundancy is always an asset;while in a real operating railway, redundancy has at times been an asset to the system and at other times has increasedcost while also decreasing performance and whole-system safety margins.This paper explores the justification for component and link redundancy in signalling system design alongside thelegislation and body of research on system resilience. It draws on a series of ideas from the field of resilienceengineering, and real-world rail and signalling examples, to explore the issues. Alarm architecture, lifecycle maintenanceplanning, and criticality assessment are provided as concrete guidance for how to design a resilient signalling system.However, true resilient behaviour depends on the context, organisational culture and human behaviours, and the realrailway as an evolving complex system.

Richard Flinders Siemens Ltd. This is a paper exploring the concept of the digitalpoint machine, or more correctly the effects theDigital Railway may have on the development ofand requirements for trackside equipment!The move to a connected system for railwaycontrol will certainly open up opportunities to alsoconnect the current ‘dumb’ devices but what willthe new scope for this connected equipment be?Will changes be driven by digitalization or willcommercial and social changes have moreimpact?Will there be significant changes at all?

Christopher Whiteside and Heather Moody Siemens Ltd Dr. Rhena Helmus Siemens AG Rail-based systems are exposed to various operational demands brought about either by high mechanical loading orexternal influences. At the same time, billions of passengers and freight goods rely on rail systems every day. Safety,availability, and reliability are key for a competitive rail-based transport. To capture any abnormal behaviour duringoperations, data is generated by various sources for a better understanding of interacting phenomena and to preventcomponent failure in advance. In order to move forward to a smart infrastructure, insights gained by the analysis ofhistorical and real time data have to be turned into actions.

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

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
