Improved Spiral Geometry for High Speed Rail
U.S. Department Of Transportation Federal Railroad Administration RR08-02 January 2008 Improved Spiral Geometry for High Speed Rail SUMMARY A different shape of spiral section for transitioning from tangent to curved track was tested on the Northeast Corridor in a 0.925-degree curve (Figure 1) near Guilford, CT, where typical operating speed for Amtrak's Acela trains is 125 mph. The modified spiral geometry was intended to reduce lateral forces and improve ride quality for high speed trains when entering and exiting curves. The modified design causes a train to rotate around its center of gravity as it leans into a curve, rather than centering rotation at the top-of-rail as does a conventional railroad spiral. Ride quality and force measurements were made before and shortly after spiral modification, and 1 year later. Compared to conventional geometry, initial and final measurements showed that the modified spirals reduced peak-to-peak lateral accelerations in the car body by 41 percent. Lateral wheel-rail force measurements from two instrumented wheelsets of an Acela power car showed a reduction in root-mean- square (RMS) net axle lateral forces of about 33 percent. Initially, truck lateral peak-to-peak acceleration dropped by 38 percent, but after 1 year, these accelerations returned to the pre-modification levels. At the test site, the modified spiral geometry was applied without the need to change rail length. The resulting shape and rate of superelevation change also fall within existing Federal Railroad Administration (FRA) track safety standard allowances. Amtrak plans to continue this study by installing the modified spiral geometry on at least two additional curves for further evaluation. -

Development and Maintenance of Class 395 High-Speed Train for UK High Speed 1
Hitachi Review Vol. 59 (2010), No. 1 39 Development and Maintenance of Class 395 High-speed Train for UK High Speed 1 Toshihiko Mochida OVERVIEW: Hitachi supplied 174 cars to consist of 29 train sets for the Class Naoaki Yamamoto 395 universal AC/DC high-speed trains able to transfer directly between the Kenjiro Goda UK’s existing network and High Speed 1, the country’s first dedicated high- speed railway line. The Class 395 was developed by applying technologies Takashi Matsushita for lighter weight and higher speed developed in Japan to the UK railway Takashi Kamei system based on the A-train concept which features a lightweight aluminum carbody and self-supporting interior module. Hitachi is also responsible for conducting operating trials to verify the reliability and ride comfort of the trains and for providing maintenance services after the trains start operation. The trains, which formally commenced commercial operation in December 2009, are helping to increase the speed of domestic services in Southeast England and it is anticipated that they will have an important role in transporting visitors between venues during the London 2012 Olympic Games. INTRODUCTION for the Eurostar international train which previously HIGH Speed 1 (HS1) is a new 109-km high-speed ran on the UK’s existing railway network. Hitachi railway line linking London to the Channel Tunnel supplied the new Class 395 high-speed train to be able [prior to completion of the whole link, the line was to run on both HS1 and the existing network as part known as the CTRL (Channel Tunnel Rail Link)]. -

Boardman Commissioner Department of Transportation State Office Building Campus – Building #5 Albany, NY 12232 Re: Turboliner Modernization Project Project Delays Report 2002-S-52 Dear Mr. Boardman: Pursuant to the State Comptroller’s authority as set forth in Article V, Section 1 of the State Constitution, and Article II, Section 8 of the State Finance Law, we have audited the progress made by the Department of Transportation on the Turboliner Modernization Project (Project) for the period October 1, 1998 through October 31, 2002. This report is the first in a series of reports we plan to issue addressing activities related to the Project. Other reports will address such topics as Project monitoring and controls over contract payments. A. Background The Department of Transportation (Department) oversees the transportation systems in New York State. In one of these systems, rail transportation between New York City and Buffalo (the Empire Corridor) is provided to passengers by the National Railroad Passenger Corporation, also known as Amtrak. To improve passenger rail transportation in the Empire Corridor, the Department is implementing the High Speed Rail Improvement Program. The Department and Amtrak have entered into a contract to support the objectives of the high-speed rail program. While this program was formally announced to the public in September 1998, some of the activities relevant to the program were initiated prior to the announcement. One of these activities was the Project, in which seven existing Amtrak trainsets were to be remanufactured so that they would be capable of traveling at 125 miles per hour, and meet current Federal safety and accessibility standards. -

Politechnika Wrocławska, Wydział Budownictwa L ądowego i Wodnego; Katedra Mostów i Kolei [email protected] DOI: 10.35117/A_ENG_19_06_01 Measurements of transverse section wear of rails in tracks of tram-loop Abstract: In article the problems of classical methods of transverse section wear of rails replacement with new techniques based on electronic devices was concerned. Reasons of rails shape section changes were defined. Principles of rails waste inspection resulting from regulations were reminded. Review of practical measurement methods and devices were made. Shapes of nominal sections of rails used in tram tracks were analyzed. Realization of measurements executed with mechanical-electronic profile gauge and mechanical track gauge on tram-loop S ępolno in Wrocław were described. Proposal of graphic manner analysis of rail wear measurements in connection with track width measurements were proposed. In summary conclusions from effected investigations were formulated. Keywords: Tram tracks; Diagnostics; Profile Gauge Introduction In August 2017, the exchange of tram switches at the intersection of Paderewski and Mickiewicz streets. At the time of these works, the S ępolno loop was excluded from streetcar traffic. The author of this article managed to obtain the infrastructure manager's approval (ZDiUM) for measurements of rail shape section wear on this loop at that time. These examinations were not the result of any order or grant but resulted only from the need to check the correct operation of diagnostic equipment used in teaching, before the beginning of the next semester of classes with students. The possibility of carrying them out, however, has become an opportunity to recognize some interesting problems that are the result of replacing the classic methods of measuring rail section wear with new techniques based on the use of electronic devices. -
Catenary 전기적 특성 Electrical Characteristics of Catenary
Catenary 전기적 특성 Electrical Characteristics of Catenary 데버랜전고팔* 노영환** 김윤호*** Devarajan Gopal Lho, Young Hwan Kim, Yoon Ho ------------------------------------------------------------------------------------ ABSTRACT In this paper, the basic requirements of catenary in railroad traction is explained. Three different types of catenary suspension systems for different terrains, environments and high speed / low speed trains are presented. The essential requirements of catenary such as reliability, cost effectiveness, maintenance and ruggedness requirements are discussed. The catenary materials and safety problems associated in it are dealt. ------------------------------------------------------------------------------------ 1. Introduction: There is a wide variety of electric traction systems around the world, which have been built according to the type of railway, its location and the technology available at the time of the installation. Many installations seen today were first built up to 100 years ago, some when electric traction was barely out its diapers, so to speak, and this has had a great influence on what is seen today. In the last 20 years there has been a gigantic acceleration in railway traction development. This has run in parallel with the development of power electronics and microprocessors/ microcomputers. What have been the accepted norms for the industry for, sometimes, 80 years, have suddenly been thrown out and replaced by fundamental changes in design, manufacture and operation. Many of these developments are highly technical and complex. To begin with, the electric railway needs a power supply that the trains can access at all times. It must be safe, economical and user friendly. It can use either DC (direct current) or AC (alternating current), the former being, for many years, simpler for railway traction purposes, the latter being better over long distances and cheaper to install but, until recently, more complicated to control at train level.
