Abstract Proposals are currently being developed for high-speed wheel-on-rail passenger train service in several intercity corridors in the United States. These proposals involve the application of foreign high-speed train technology, and operation at speeds exceeding 125 mph. This report provides an assessment of safety issues associated with high-speed rail passenger systems, and identifies where further research may be needed to ensure the safe operation of such systems in the United States railroad environment. The approach taken in this assessment was to first "identify and describe the key safety-related features of all high-speed rail systems that may be applied in the United States. Then all safety issues associated with passenger rail systems are identified, and pertinent safety-related regulations, standards and practices applicable in the U.S. and on foreign systems are discussed. Each discussion concludes with a recommendation regarding the need for research into the safety issue: The principal issues on which research appears desirable include passenger car structural strength requirements, novel brake system performance, security of the right-of-way against obstructions, and high-speed signalling and train control systems. 17.

    Shinkansen - Wikipedia 7/3/20, 10)48 AM Shinkansen The Shinkansen (Japanese: 新幹線, pronounced [ɕiŋkaꜜɰ̃ seɴ], lit. ''new trunk line''), colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, in order to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network.[1][2] It is operated by five Japan Railways Group companies. A lineup of JR East Shinkansen trains in October Over the Shinkansen's 50-plus year history, carrying 2012 over 10 billion passengers, there has been not a single passenger fatality or injury due to train accidents.[3] Starting with the Tōkaidō Shinkansen (515.4 km, 320.3 mi) in 1964,[4] the network has expanded to currently consist of 2,764.6 km (1,717.8 mi) of lines with maximum speeds of 240–320 km/h (150– 200 mph), 283.5 km (176.2 mi) of Mini-Shinkansen lines with a maximum speed of 130 km/h (80 mph), and 10.3 km (6.4 mi) of spur lines with Shinkansen services.[5] The network presently links most major A lineup of JR West Shinkansen trains in October cities on the islands of Honshu and Kyushu, and 2008 Hakodate on northern island of Hokkaido, with an extension to Sapporo under construction and scheduled to commence in March 2031.[6] The maximum operating speed is 320 km/h (200 mph) (on a 387.5 km section of the Tōhoku Shinkansen).[7] Test runs have reached 443 km/h (275 mph) for conventional rail in 1996, and up to a world record 603 km/h (375 mph) for SCMaglev trains in April 2015.[8] The original Tōkaidō Shinkansen, connecting Tokyo, Nagoya and Osaka, three of Japan's largest cities, is one of the world's busiest high-speed rail lines.

  • K Novel Technologies
    Rocky Mountain Rail Authority High‐Speed Rail Feasibility Study Business Plan ‐ Appendices K Novel Technologies A key requirement of this study is that all proposed technologies should be proven and capable of receiving required regulatory approvals within the implementation time scales of the project. The study has assessed proven technology options and their potential speed, focusing on existing technologies that have been proven in actual revenue service. Proposed “Novel” or new technologies that are still under development cannot be considered practical for this study unless they can show that they can be implemented within a 5‐10 year time horizon. This includes meeting FRA/FTA safety regulatory requirements as well as demonstrating the practical capability to commercially operate in the Colorado environment. Accordingly, and consistent with the scope of the I‐70 Draft PEIS, it has focused on rail and Maglev‐based technologies. Various groups have advocated new or “novel” technologies for potential application to the Colorado corridors. However, the RMRA funding grant from the Colorado Department of Transportation specifically excluded detailed consideration of “novel” technologies from this study, restricting application of funds only to proven technologies: 1. The CDOT Transportation Commission Resolution Restricting Front Range Commuter Rail Study passed 6 to 1 in November 2006. 2. DMU, EMU, Diesel Locomotive Hauled or Magnetic Levitation are the only technologies allowed by the Transportation Commission because of work done previously in I‐70 Draft PEIS. Per this direction from the RMRA and CDOT, “novel” technologies cannot be evaluated at the same level as “proven” technologies. Nonetheless, a survey was conducted that includes novel technologies so we can understand their development potential for possible long‐run implementation.
