The work comes after infrastructure manager Bane Nor awarded the company contracts worth NKr 1.8bn ($US 222m) to equip the country\u2019s entire mainline train fleet of 467 trains of 55 different types with ERTMS and maintain their systems for up to 25 years.\r\n\r\nBane Nor says the onboard software consists of one generic and one specific application. Both applications will undergo extensive tests at Alstom\u2019s factory, while the generic application (GA) will also be installed and tested in three vehicles: a Di8 diesel locomotive owned by Norwegian State Railways (NSB), a LTR 17 loading tractor from infrastructure manager Bane Nor and a Type 75 train from Norwegian Trains.\r\n\r\nAs well as finding space for the new components, Alstom must also integrate ETCS with the train\u2019s braking system and other control systems.\r\n\r\nTo study the train\u2019s designs and installations and see which interfaces already exist inside the trains, Alstom was allowed to inspect all vehicle types during the bidding phase. After the contract was signed in June last year, Alstom has since studied the vehicles\u2019 documentation and conducted working meetings with vehicle experts from NSB, Bane Nor and Norske Tog to clarify any uncertainties and discuss various solutions.\r\n\r\n\r\n\r\nAlstom then undertook detailed inspections to find out how the equipment could be installed in the trains, where cables could be placed and what equipment must be removed. Based on drawings and 3D scans, Alstom has developed models that visualise where the new components should be placed and how they should be integrated with the existing systems.\r\n\r\nAs well as engineers and vehicle experts, ergonomic specialists are also involved in the design and placement of components in the driver\u2019s cab to improve the ergonomics as well as oversee the installation of acoustic and visual alarms.\r\n\r\nAlstom is now in the process of completing the inspection reports for the three test trains after which a final design will be prepared in close collaboration with the vehicle owners.\r\n\r\nThe processes outlining the design, installation and approval of ERTMS developed during the study will form the basis for the deployment of ETCS on rail vehicles in Norway.\r\n\r\nThe trains will be rebuilt at Bane Nor Property\u2019s workshop in Grorud, with installation and quality control due to begin in November and December. The equipment will then be tested at the workshop before tests on the Roa - H\u00f8nefoss line begin in 2020.
