A £400 million rail project is underway in Neath Port Talbot, Wales, to establish the Global Centre of Rail Excellence for testing new trains, including hydrogen-powered models. The site, built on a 700-hectare area near Onllwyn village, will not be accessible to the general public but will serve as a crucial research and testing facility for the UK and European rail markets. The project is expected to be fully operational by 2027, offering round-the-clock testing on two looped tracks. This initiative aims to advance rail technology by allowing products to be tested at high technology readiness levels in a live environment. The project has received significant funding from the Welsh and UK governments and aims to create job opportunities while attracting companies for cutting-edge transport testing. Despite the need to secure additional funding, the project has made substantial progress towards its completion, with a strong emphasis on innovation and economic development for the region.
