About GCRE

GCRE will become the ‘one stop shop’ for railway innovation, from research and development, through testing and verification, to applied innovation on mainline passenger and freight railways.


Situated on the former Nant Helen opencast site and Onllwyn Washery in Neath Port Talbot and Powys in South Wales, the 550 hectare facility will include two test loops, one being a 6.9km electrified high speed rolling stock track with a maximum speed of 177km/h and the other a 4km 65km/h test track. Other facilities will include a dual-platform test environment, rolling stock storage and maintenance facilities, operations and control offices, staff accommodation, shunting staff facilities and connections to the nearby main line.


There will also be state of the art IP secure testing environments; equipment, systems and communications development facilities. Education, training, visitor and conference facilities are all envisaged in the wider site.
