ERTMS/ETCS Railway Signalling Appendix A ERTMS/ETCS Railway Signalling Salvatore Sabina, Fabio Poli and Nazelie Kassabian A.1 Interoperable Constituents The basic interoperability constituents in the Control-Command and Signalling Sub- systems are, respectively, defined in TableA.1 for the Control-Command and Sig- nalling On-board Subsystem [1] and TableA.2 for the Control-Command and Sig- nalling Trackside Subsystem [1]. The functions of basic interoperability constituents may be combined to form a group. This group is then defined by those functions and by its remaining exter- nal interfaces. If a group is formed in this way, it shall be considered as an inter- operability constituent. TableA.3 lists the groups of interoperability constituents of the Control-Command and Signalling On-board Subsystem [1]. TableA.4 lists the groups of interoperability constituents of the Control-Command and Signalling Trackside Subsystem [1]. S.

Signalling A.2 Cross-Talk Protected Zone To define a cross-talk protected zone, let us first provide the definition of the following coordinate system used for the orientation of the Balise and the Antenna Unit of the Eurobalise Transmission System with respect to the rail direction; see Fig. A.1: • A reference axis in parallel with the rails (the X-axis), • A reference axis at right angles across the rails, and which is level with the top of rails (the Y-axis), • A reference axis directed upwards, at right angles to the rail plane (the Z-axis). The Balise has reference marks on each of the six sides that indicate the positions of the three axes, related to the electrical centre of the Balise. The Antenna Unit has reference marks on each of the six sides that indicate the positions of the X-, Y-, and Z-axes, respectively. Based on such reference axis, Table A.5 provides the definition of the cross- talk protected zone.

European Initiative Linking Interlocking Subsystems Situation: • You are an infra manager (…. passenger, tax payer) • Expectations concerning signalling • Huge installed base • Many generations of equipment • Obsolete within 10..20 years • Not enough budget to replace And you know: “At all European railways these problems are similar …” EULYNX 2 What is the problem?

What is EULYNX?

  • CBTC Test Simulation Bench
    Computers in Railways XII 485 CBTC test simulation bench J. M. Mera, I. Gómez-Rey & E. Rodrigo CITEF (Railway Technology Research Centre), Escuela Técnica Superior de Ingenieros Industriales, Universidad Politécnica de Madrid, Spain Abstract Due to its safety characteristics, signalling equipment requires a great amount of testing and validation during the different stages of its life cycle, and particularly during the installation and commissioning of a new line or upgrade of an existing line, the latter being even more complicated due to the short engineering periods available overnight. This project aims to develop a tool to reduce the above-mentioned efforts by simulating the CBTC trackside, fulfilling the interfaces between subsystems and elements of these subsystems, and using some real elements. In this way, a testing environment for signalling equipment and data has been developed for the CBTC system. The aims of the project that were set out at the beginning of the development and completed with the present simulator are as follows: Real CBTC equipment trials and integration: CBTC on-board equipment, CBTC Radio Centre, etc. Other signalling elements trials and integration: interlockings and SCCs. CBTC track data validation. In order to achieve these objectives, various simulation applications have been developed, of which the most important are the following: Infrastructure, Automatic trains, Train systems, Planning and Control Desk, etc. This system has been developed, and is currently adding new modules and functionalities, for companies of the Invensys Group: Westinghouse Rail WIT Transactions on The Built Environment, Vol 114, © 2010 WIT Press www.witpress.com, ISSN 1743-3509 (on-line) doi:10.2495/CR100451 486 Computers in Railways XII Systems in the UK and Dimetronic Signals in Spain, which are using it for the new CBTC lines under their responsibility.

  • Balise Lifecheck the Control of Balises Is Mainly Manual and Often Basic
    utomation of Balise A maintenance Balise LifeCheck The control of balises is mainly manual and often basic. There are several tools available on the market to help performing balise maintenance, but a vast majority of them follow a corrective approach. ERTMS Solutions’ BaliseLifeCheck is the only on-board tool able to do predictive maintenance. he Tsolution • Compatibility with all balises’ and legacy KER balises (KVB, EBICAB,...) • Geolocalization of the balises and creation of a cartography • Detection of possible Big Metal Masses on the track that will affect BTM performances • Computation of a signature on measurements • Auto-marking on all balises matching signature • Generation of a full report after each test journey The BaliseLifeCheck is a preventive balise measurement instrument that can be used on both diagnostic and commercial trains. While capable of measuring balise, the BaliseLifeCheck is also highly customizable and can be set-up to deliver preventive maintenance to any ‘legacy’ Automatic Train Protection (ATP) balises, regardless if they are fitted or not with ERTMS. The Benefits On-board The system has been designed to be installed on-board a test or maintenance train which purpose is to analyze test tracks and active lines. Measurement It measures key electrical parameters of the up link signal and verifies if they comply with the requirements of Subset-036 in the case of ETCS balises. In this case some measurements/tests are performed against requirements of Subset-085. Diagnosis The main goal of the tool is to provide measurements and evidences which assess the correct behavior of balises that are already deployed on the field.

  • Heavy Haul Freight Transportation System: Autohaul Autonomous Heavy Haul Freight Train Achieved in Australia
    FEATURED ARTICLES Advanced Railway Systems through Digital Technology Heavy Haul Freight Transportation System: AutoHaul Autonomous Heavy Haul Freight Train Achieved in Australia There are many iron ore rail lines in the Pilbara region, located in North-West Australia. Global mining company Rio Tinto Limited operates a fleet of heavy haul iron ore trains 24 hours a day from its 16 mines to four port terminals overlooking the Indian Ocean. To increase their operational capacity and reduce transportation time, Rio Tinto realized that driverless (GoA4) operation of its trains was the way to achieve this. The company established a framework agreement with Hitachi Rail STS S.p.A. This project was named AutoHaul, and two companies worked closely on its development over several years. Since completing the first loaded run in July 2018, these trains have now safely travelled more than 11 million km autonomously. The network is the world’s first driverless heavy haul long distance train operation.

  • Relative Capacity and Performance of Fixed- and Moving-Block Control
    Research Article Transportation Research Record 1–12 Ó National Academy of Sciences: Relative Capacity and Performance of Transportation Research Board 2019 Article reuse guidelines: sagepub.com/journals-permissions Fixed- and Moving-Block Control DOI: 10.1177/0361198119841852 Systems on North American Freight journals.sagepub.com/home/trr Railway Lines and Shared Passenger Corridors C. Tyler Dick1, Darkhan Mussanov1,2, Leonel E. Evans1, Geordie S. Roscoe1, and Tzu-Yu Chang1 Abstract North American railroads are facing increasing demand for safe, efficient, and reliable freight and passenger transportation. The high cost of constructing additional track infrastructure to increase capacity and improve reliability provides railroads with a strong financial motivation to increase the productivity of their existing mainlines by reducing the headway between trains. The objective of this research is to assess potential for advanced Positive Train Control (PTC) systems with virtual and moving blocks to improve the capacity and performance of Class 1 railroad mainline corridors. Rail Traffic Controller software is used to simulate and compare the delay performance and capacity of train operations on a representative rail cor- ridor under fixed wayside block signals and moving blocks. The experiment also investigates possible interactions between the capacity benefits of moving blocks and traffic volume, traffic composition, and amount of second main track. Moving blocks can increase the capacity of single-track corridors by several trains per day, serving as an effective substitute to con- struction of additional second main track infrastructure in the short term. Moving blocks are shown to have the greatest capacity benefit when the corridor has more second main track and traffic volumes are high.
