This issue is important, as high levels of traction currents can have not only prevents, but also a dangerous impact on the equipment of railway automation devices. It is necessary to investigate the propagation of traction currents and potentials along the rails. Objective: Investigate the propagation of traction currents and potentials along the rails, the determination of critical currents, which not executed tone track circuits modes. Methods: In order to investigate the mathematical model, and the method of calculation tone track circuits modes was used. Results: By means of mathematical model, which includes being several rolling-stocks at the feeder zone, different rail resistance and isolation, the diagrams of currents and potentials propagations for DC and AC electric traction have been obtained. A comparative analysis of the experimental data and the results of the investigation has been realized. Based on received levels of reverse traction current their influence on track circuit modes has been investigated. Conclusions: The reverse traction current level near the substation and rolling-stock can be more than 600A. Great reverse traction current levels have an influence on tonal track circuit functioning, namely normal and shunt modes. When the traction current arrives 200 A there is a reduction criteria of tonal track circuits.","PeriodicalId":338885,"journal":{"name":"Science and Transport Progress","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133236421","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}
