The Tokaido Shinkansen commenced operation on October When the Tokaido Shinkansen commenced operation, 1, 1964 and is about to reach its 50th anniversary. The there were 60 departures per day in a “1-1” hourly timetable Tokaido Shinkansen, which takes on the role of Japan’s with one Hikari, stopping only at major stations, and one main transportation artery, has served 5.6 billion passengers Kodama, stopping at each station. The travel time of Hikari since its start and propped up Japan’s economy. Ever since between Tokyo and Shin-Osaka was 4 hours. the operation commenced, the Tokaido Shinkansen has Subsequently, the number of train departures was maintained a flawless record of no train accidents resulting increased time and again with the “2-2” and “3-3” hourly in fatalities or injuries of passengers onboard, and has timetables.

  • Uredas, URGENT EARTHQUAKE DETECTION and ALARM SYSTEM, NOW and FUTURE
    13th World Conference on Earthquake Engineering Vancouver, B.C., Canada August 1-6, 2004 Paper No. 908 UrEDAS, URGENT EARTHQUAKE DETECTION AND ALARM SYSTEM, NOW AND FUTURE Yutaka NAKAMURA 1 SUMMARY UrEDAS, Urgent Earthquake Detection and Alarm System, can realize the real-time early earthquake detection and alarm system in the world. There is a local government that has realized a tsunami warning system using real-time estimated earthquake parameters as magnitude and location, distributed by UrEDAS. On 26th May 2003, the Miyagiken-Oki Earthquake was occurred. It was so large that the maximum acceleration of about 600 Gal was observed along the Shinkansen line and 23 columns of the rigid frame viaducts (RC) were severely cracked. This earthquake occurred on the business hours of the Shinkansen. As expected, coastline “Compact UrEDAS” along the Shinkansen took out the early P-wave alarm before the destructive earthquake motion and the validity of this system was proved for the first time. INTRODUCTION UrEDAS is the only real time P-wave alarm system over the world on practical use. It is characterized to be able to process digitized waveform step by step without saving. Amount of procedure does not differs either earthquake occurs or not, so failure because of over load will not occur. The 2003 Miyagiken-Oki earthquake (Mj 7.1) occurred on 26th May, Compact UrEDAS worked as expected. It was for the first time that the validity of the early warning system was verified under circumstances of big earthquake such as rigid frame viaducts of Shinkansen were damaged. In this paper, the present condition of P-wave early detection system UrEDAS will be viewed referring to cases at work, also result of test observation where faults exists will be reported.

  • The Body Inclining System of the Series N700 Shinkansen
    The Japan Society of Mechanical Engineers International Symposium on Speed-up, Safety and Service Technology for Railway and Maglev Systems 2009 (STECH’09) 2009.6.16-19 Niigata JAPAN THE BODY INCLINING SYSTEM OF THE SERIES N700 SHINKANSEN Yasuki Nakakura *1 and Kosuke Hayakawa *2 *1 Shinkansen Operations Division, Central Japan Railway Company, [email protected] *2 Shinkansen Operations Division, Central Japan Railway Company, [email protected] ABSTRACT 2. OVERVIEW OF THE BODY INCLINING The Series N700 is the first Shinkansen rolling stock to SYSTEM employ a body inclining system, which allows speed increases on curves while maintaining riding comfort. 2.1 Requirements of the body inclining system for a For use in the Tokaido Shinkansen, such a system needs Tokaido Shinkansen train-set to be light-weight and possess a reliable means to provide Over the years, body inclining system has been used with high precision position data. Reliability is a crucial factor conventional trains, but no such system has been when considering that the Tokaido Shinkansen operates a employed in Shinkansens excluding cases of test use. maximum of 13 train-sets per hour. In order to meet these Looking at high-speed trains in Europe, there exist cases requirements, the Series N700 adopts a simple and light where body-inclining mechanisms have been adopted weight air-spring based body inclining mechanism, such as the Italian ETR450 and the Swedish X2000. which combines the new automatic train control (ATC) However, their mechanisms are complex and heavy, technology capable of providing reliable high-precision making them unsuitable for use in the Tokaido position data, and control transmission technology that Shinkansen, where axle load restriction is strict.
