The 1998 Track Safety Standards and 1999 Passenger Equipment Safety Standards provide comprehensive requirements for the qualification and operation of passenger equipment. Among many safety issues, these standards address the response of rolling stock at speed to track deviations, and the potential for derailment and/or injury to passengers. The principles contained in the Safety Standards are also used by FRA to evaluate safety performance of vehicles for operation at high cant deficiency for speeds less than 90 mph as part of FRA's waiver process. This paper describes the types of static and dynamic tests and equipment that are required with respect to vehicle-track interaction to demonstrate compliance of new equipment with the Standards, and the technical fundamentals behind the requirements. Examples include the National Railroad Passenger Corporation's (Amtrak's) experiences in applying for waivers and qualifying new equipment under these regulations, particularly the high cant deficiency testing of the Talgo train in the Pacific Northwest, and the high-speed and high cant deficiency testing of Maryland Rail Commuter's (MARC's) MARC-III bi-level cars, Acela Express trainsets and Amtrak's high-horsepower electric locomotives in the Northeast Corridor. In addition, technical data and procedures necessary to have existing equipment approved for operation at higher speed or cant deficiency are also described. This paper highlights nuances of the new regulations and common misinterpretations.","PeriodicalId":413474,"journal":{"name":"ASME/IEEE Joint Railroad Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125418960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The contact model has been developed both through external subroutines (used to develop the friction model and the determination of the creepages) and using standard element of the MBS code (used to define the kinematic constraints of the wheel). This model can be introduced in a general railway vehicle model with no limitations: each \"contact element\" so defined can be applied between two bodies of the MBS the one representing the wheel, the other the rail or the roller. It is possible to choose among several algorithms to solve the friction problem: the Fastsim code, the Polach's method, the linearized Kalker method or a simplified analytical method with saturation. It is also possible to perform simulations using constant value for the friction coefficient and for the normal load (fast simulations) or to use a nonlinear law for the friction coefficient and the actual value for the normal load on the wheel. Due to the structure of the code it is possible to change the shape of the wheels profiles during the simulations even if at the moment this features has not been introduced in the code. Finally, in the paper the behavior of a bogie on rail and on a roller is compared.","PeriodicalId":413474,"journal":{"name":"ASME/IEEE Joint Railroad Conference","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114495061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In compliance with this requirement, twelve high-speed Acela coaches, operating in the Northeast Corridor between Boston, MA, and Washington DC, have been equipped with remote monitoring systems. The systems provide continuous measurement of car body and truck motions, detect various acceleration events, tag them with GPS time and location information, and deliver the data to central processing stations through wireless communications channels. The central processing stations installed at the National Railroad Passenger Corporation (Amtrak) and ENSCO, Inc., headquarters provide e-mail and pager notifications to designated Amtrak officers and also make the data available to them over secure Intranet and Internet connections. The overall architecture has multiple levels of protection and redundancy in order to ensure high reliability and availability of the service. The systems have been in continuous operation for over a year and provided a multitude of valuable information. Examples of system-reported acceleration events include events caused by track irregularities and train handling. The paper also describes some of the real-life operational scenarios and situations that arise when autonomous remote monitoring systems are used, including wireless communications coverage issues, GPS location pitfalls, and maintenance issues.","PeriodicalId":413474,"journal":{"name":"ASME/IEEE Joint Railroad Conference","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126228530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
