It then moves on to explore the technological opportunities and necessities facing railway control systems engineers. It explores too the quest for improved performance, and the need to focus not just on safety, but to contribute to the delivery of a cost-effective, efficient and environmentally friendly railway as well. Finally, the author briefly considers the skills and expertise we will need to deliver the systems of the future.","PeriodicalId":277736,"journal":{"name":"Railway Gazette international","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121714770","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 new system, known locally as Head-On Generation (HOG) is expected to reduce IR's annual energy consumption by around 700,00 kWh for every 24-coach train converted, thus having an immense positive impact on the environment in terms of reducing annual greenhouse gas emissions and reducing noise pollution. IR will receive a significant carbon credit, which will help to justify the cost of the conversion.","PeriodicalId":277736,"journal":{"name":"Railway Gazette international","volume":"167 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129472038","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}
