Keymile will provide the telecommunications backbone to support train operation on the new line. This will be a hybrid system comprising an SDH network and Gigabit Ethernet\/IP. It will be based on Keymile's MileGate platform which will enable the system to be operated as a modular Ethernet\/IP switch, an SDH\/PDH multiplexer or as a combination of the two. The system will transmit a variety of data including that needed for railway signalling, traction current, cross-wind detection, CCTV, and telephone calls.\r\nKeymile will also provide components, servers, software and UNEM network management software, as well as service support for up to 19 years.\r\nConstruction of the line started in 2012. Tracklaying is scheduled to begin in early 2015 along with electrification and construction of the first signalling buildings. The line is due to open in May 2017.
