Work is underway on the new £200 million Global Centre of Rail Excellence (GCRE), a world-class rail testing facility which is set to open in 2025.

Various tier one contractors have now been appointed including Hirwaun-based Walters Group who will work with Atkins to prepare the site for construction.

Arcadis are developing the rail systems design and Mott MacDonald is focused on the net zero energy strategy.

A multidisciplinary team has also been appointed to produce an overarching masterplan for the transformation of the 475-hectare site.

This follows a competitive tender process led by the Design Commission for Wales who are advising on the development of GCRE.

The major infrastructure project will transform the site of the former Nant Helen Opencast Mine and Onllwyn Washery at the head of the Dulais and Tawe Valleys in south Wales into a global hub for rolling stock and infrastructure testing, innovation, storage and maintenance.


It will be used by the UK and international rail industry and is expected to create over 100 jobs directly and be a catalyst for creating many more as academic and industrial partners are attracted to the site.

GCRE was established by the Welsh Government as a Special Purpose Vehicle (SPV) in 2021 with an initial commitment of £50 million.

The UK Government is expected to confirm a further £10 million for research and development along with capital funding of £20 million.

An investment prospectus to attract private funding for the project is also in development ready for launch in the autumn of 2022.

Outline planning consent for the project was granted by Neath Port Talbot Council and Powys County Council in 2021.

Debra Williams, Chair of GCRE,  said: “This is an ambitious infrastructure project that has the potential to transform the local area with a £200 million investment that will put Wales and the UK at the very heart of 21st century sustainable transport innovation.

“Featuring the UK’s first net zero railway, GCRE will include a modern and comprehensive rail testing and innovation facility with capacity and capabilities for rigorous testing of rolling stock, infrastructure, and integrated systems from prototype to implementation.”


Simon Jones, Chief Executive of GCRE, added: “GCRE will be unique in Europe and is a major economic development project for Wales.

“It will support the railway industry to meet the challenges of reducing costs through innovation, improving reliability and passenger experience, and helping to reduce greenhouse gas emissions.

“With the support of our key stakeholders including Neath Port Talbot and Powys County Councils, GCRE will play a pivotal role for the public and private sector partners of the railway in the UK and overseas. “

“Nant Helen was one of the last opencast coal mines in Wales. The development of GCRE will establish a progressive, post-carbon future for the site; providing much needed state-of-the-art rolling stock testing, infrastructure testing, storage and maintenance facilities for the international rail industry and creating jobs for local people.”

Walters Director, Kevin Llewellyn said: “We are delighted to have secured this project, the site for which is just 10 miles from our head office in Hirwaun.

“As a local employer we are grateful for the recognition and support of GCRE Limited in awarding us this contract. Our unrivalled experience with design partner, Atkins, will see this exciting project set the stage for what will undoubtedly be a world class facility.”
