The task force identified several ways to prevent the intrusion of the iron dust particles by sealing the autorack cars or by constructing air flow barriers. Building upon this research, Burlington Northern Railroad's (BN's) Research and Development Department has identified and measured the source of iron dust contamination along its roadbeds. BN also developed specific means to contain or eliminate the particles. The BN design uses magnetic skirts mounted at the outboard sides of the trucks at both ends of autorack cars. The magnetic skirts attract the the iron dust particles and prevent many from rising from the track. Some vulcanized rubber stripping is also applied to seal airgaps at specific locations on autorack test cars. A prototype autorack car equipped with magnetic skirts has been tested in regular automotive train service since July 1991. The test results demonstrate that the skirts are very effective.<<ETX>>","PeriodicalId":302168,"journal":{"name":"Proceedings of the 1993 IEEE/ASME Joint Railroad Conference","volume":"42 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":"122844203","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 are three problems to be solved for the actual application of a DC chopper in electric railways. The first is the realization of a high-voltage chopper, the second is the reduction of inductive interference, and the third is the reduction of weight and cost of chopper equipment. The design principles of SCR choppers and GTO choppers are compared. Some of the simplified circuit diagrams for the proposed DC chopper design are discussed. The commerical availability of a 0-1500 V DC chopper that can be incorporated into an existing locomotive design is investigated and some of actual DC chopper controller circuits for the traction and locomotive systems produced by different vendors are discussed.<<ETX>>","PeriodicalId":302168,"journal":{"name":"Proceedings of the 1993 IEEE/ASME Joint Railroad Conference","volume":"41 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":"124967977","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 preliminary economic analysis has shown that the viability of AC traction in North America lies in the fleet reduction that the specification performance levels, when implemented, can bring. However, if fleet reliability does not increase in proportion to fleet reduction, then both projected savings and viability are reduced. A study of maintenance and reliability is performed for several key European fleets of AC traction locomotives, defined in the initial AAR design assessment. Several visits were made to these European railways to gather information and review their service experience. The resulting information is revealed, with respect to the AAR Performance Specification for AC Traction Systems. The European information centers on early failure data and current reliability targets for new equipment. The performance specification is also outlined.<<ETX>>","PeriodicalId":302168,"journal":{"name":"Proceedings of the 1993 IEEE/ASME Joint Railroad Conference","volume":"467 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":"123259088","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 network management system described is a proposed system for inclusion in North American railroads as they implement an ATCS subnetwork.
