The application of DOME for two kinds of conventional signaling systems, the speed indicating cab-signal system and the conventional AWS system, is explained. The features of the ATS-S type automatic warning system are explained.<<ETX>>","PeriodicalId":302168,"journal":{"name":"Proceedings of the 1993 IEEE/ASME Joint Railroad Conference","volume":"885 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127764764","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}

Motoring and braking performance of a state-of-the-art transit vehicle propulsion inverter is presented. The impact of wheel diameter wear tolerances on motor current balance and adhesion is described. The selection of substation voltage is discussed in terms of energy recuperation from the AC propulsion system while in the electric braking mode. Finally, some of the issues relative to the selection of a track signaling system that is electromagnetically best suited for use with the AC propelled vehicles are considered.<<ETX>>","PeriodicalId":302168,"journal":{"name":"Proceedings of the 1993 IEEE/ASME Joint Railroad Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132258514","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}

This includes wheel slip/spin effects and the effects of different wheel diameters on the loading of the motors. These effects are governed by a complex interaction between the motor, its controller and wheel-rail adhesion characteristics. This work presents a dynamic model of the wheel-rail adhesion characteristics which may be expanded to simulate a multi-three phase motor driven locomotive. The model is capable of showing wheel slip effects and the effects of variations in wheel diameters on the motors. Simulations were performed on the dynamic systems simulator, SIMULINK and the results are given for several simplified cases.<<ETX>>","PeriodicalId":302168,"journal":{"name":"Proceedings of the 1993 IEEE/ASME Joint Railroad Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114804898","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}

Entire electromechanical systems such as railway locomotives can be easily simulated. Interaction between system components, which are often complex and difficult to analyse, can be easily studied. A simulation of a DC motor drive supplied from a single phase source is implemented.

This approach is necessary because there are virtually no experimental data extant which provide a quantitative measure of rail vehicle and rail vehicle occupant collision response (e.g., electronically recorded vehicle acceleration-time histories and force-deflection characteristics, high-speed films of vehicle and dummy kinematics, recorded and/or calculated occupant injury parameters, etc.).<<ETX>>","PeriodicalId":302168,"journal":{"name":"Proceedings of the 1993 IEEE/ASME Joint Railroad Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134130003","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}

A special test vehicle was designed and constructed by the Association of American Railroads (AAR) for the purpose of applying controlled levels of lateral load at the coupler pin of any adjacent car and while in motion. This test vehicle is used in determining the maximum lateral coupler load that can be safely applied to any candidate car under various curving and speed conditions. Analytical methods are also developed for predicting the coupler angles and forces generated under any given buff or draft conditions, track curvature, and coupling arrangements. The proposed method combines testing with analysis in order to determine the level of buff or draft force at which the lateral coupler load test limits are exceeded. As an example for the method, the developed techniques are used to examine the curving performance of a standard 89-ft flatcar when coupled to another relatively short 2-axle flatcar. The results indicate that the coupling of the two cars reduces the curving stability of the long flatcar under realizable buff and draft conditions.<<ETX>>","PeriodicalId":302168,"journal":{"name":"Proceedings of the 1993 IEEE/ASME Joint Railroad Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129525103","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}

There is no fundamental problem with the HSGT technologies, but rather it is with the market for the service being too small-essentially an air travel market. To expand the market, and hence benefits, the transportation function of HSGT systems must be changed, so they serve the much larger markets of intercity travel dominated by motorists. An HSGT system designed to achieve this, by carrying autos with passenger-occupants, is sketched, and questions related to its feasibility are addressed. Such service would be far more suited to US travel patterns and lifestyles, and it would be compatible with offering of conventional passengers-in-HSGT-passenger-car service on the same lines. Synergistic aspects of such a system with intelligent vehicle/highway systems (IVHS) are discussed.<<ETX>>","PeriodicalId":302168,"journal":{"name":"Proceedings of the 1993 IEEE/ASME Joint Railroad Conference","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121267322","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}
