Hitachi Rail UK is set to test new British-built trains, battery technology and digital solutions at a world-leading testing facility in Wales. Hitachi will use the Global Centre of Rail Excellence (GCRE), a new 400-million pound (about 460 million euro) facility to test future rolling stock. It will also help refine Hitachi’s battery technology, which has been co-developed with the UK arm of Turntide, an electrification technology developer, based in Sunderland. Hitachi and GCRE are collaborating to make the South Wales site a hub for digital rail technology by testing both digital signalling and infrastructure monitoring solutions.
