  • 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. Mazahir Yusuf Anthony MacDonald, Ph.D. Roslyn Stuart Hiroko Miyazaki Tinto’s Operations Center in Perth more than 1,500 km away (see Figure 1 and Figure 2). Th e operation of this 1.

  • 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.

It is also under- taking work to determine whether ETCS Level 3 technology could be used to speed up the deployment of ERTMS to within 15 years. Implementing ERTMS with ETCS Level 3 has the potential to increase railway route capacity and flexibility, and to reduce both capital and operating costs. It would also make it possible to manage rail traffic using a moving block signal- ling approach. This POSTbrief introduces ERTMS, explains the concept of moving block sig- nalling and discusses the potential benefits for rail capacity, which are likely to vary significantly between routes. Research in this area is conducted by a range of organizations from across in- dustry, academia and Government. Not all of the results of that work are publi- cally available. This briefing draws on information from interviews with experts from academia and industry and a sample of the publically available literature.

  • Application of Communication Based Moving Block Systems on Existing Metro Lines
    Computers in Railways X 391 Application of communication based Moving Block systems on existing metro lines L. Lindqvist1 & R. Jadhav2 1Centre of Excellence, Bombardier Transportation, Spain 2Sales, Bombardier Transportation, USA Abstract The unique features of Communication Based Train Control (CBTC) systems with Moving Block (MB) capability makes them uniquely suited for application ‘on top’ of existing Mass Transit or Metro systems, permitting a capacity increase in these systems. This paper defines and describes the features of modern CBTC Moving Block systems such as the Bombardier* CITYFLO* 450 or CITYFLO 650 solutions that make them suited for ‘overlay’ application ‘on top’ of the existing systems and gives an example of such an application in a main European Metro. Note: *Trademark (s) of Bombardier Inc. or its subsidiaries. Keywords: CBTC, Moving Block, CITYFLO, TRS, Movement Authority, norming point, headway. 1 Introduction The use of radio as a method of communication between the train and wayside in Mass Transit systems, instead of the traditional track circuits/axle counters and loops is gaining popularity. The radio based CBTC systems are uniquely suited for application ‘on top’ of existing Mass Transit or Metro systems for increased traffic capacity as CBTC systems normally do not interfere with the existing systems. This allows an installation of the CBTC system in a line in operation whilst maintaining full safety and capacity during the process. The fact that CBTC systems also allow Moving Block operation adds to the

  • Translating Train Management to Norway
    Translating Train Management to Norway Lasse Gullvåg Sætre Master thesis at the Center for Technology, Innovation and Culture Supervised by: Tone Druglitrø and Helge Ryggvik University of Oslo Norway, May 2017 I, Lasse Gullvåg Sætre, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Abstract This thesis explores the transition of Norwegian rail signaling from me- chanically to digitally based systems, delving into the translations of the European standard ERTMS to Norwegian railways. Through digital, tech- nical and bureaucratic informants, this study investigates the preparations and makings of what promises to be one of the biggest revolutions in the technology to date. The ERTMS is a railway signaling technology, an EU political technology, and a case of digitalized European information infrastructures, known by many names, such as smart cities or intelligent services. Studied through the Norwegian railway system’s digital integra- tion towards Europe during the last 20 years, this thesis inquires into the material semiotic production of rail governance in the Norwegian context, as well as what it means to be an EEA member. From expert informers from the Norwegian infrastructure manager Jernbaneverket and its partial successor Bane NOR, through documents and field studies/interventions, the ways in which key players of the Norwegian and European railway sectors change are explored, mapping out the issue of signaling, and how players prepare for a transition that was always part of larger ideas of mo- bility, machines and governance, extending far out from rail space.
