Britain's First Electrified Rail Test Loop Opens at Long Marston

The UK's railway innovation sector has received a significant boost with the opening of Britain's first dedicated electrified testing loop at the Long Marston Rail Innovation Centre in Warwickshire.

Rail Minister Lord Hendy officially inaugurated the new facility during a launch event attended by rail industry leaders, apprentices and local schoolchildren, marking a major milestone in the development of advanced rail testing and innovation capabilities in the UK.

The new 3.5-kilometre electrified circuit forms part of a wider £75 million investment by Porterbrook to transform the former railway site into a world-class rail research, testing and development centre.

Located on a 135-acre site, the facility has been designed to support the next generation of rolling stock, traction technologies and railway systems, providing a dedicated environment where new trains and innovations can be trialled before entering passenger service.

Lord Hendy said the centre would play an important role in supporting the future of Britain's railways, helping the industry develop and test the technologies that will underpin future services.

He described the facility as an example of the type of innovation needed as the rail sector prepares for the introduction of Great British Railways and wider industry reform.

The launch event brought together representatives from across the rail industry alongside Network Rail apprentices and local primary school pupils who had participated in educational activities linked to the project.

For Porterbrook, the opening represents the latest stage in a broader investment strategy that has seen the company deploy more than £1 billion into rail projects over the past five years.

Chief Executive Mary Grant said the Long Marston facility had been developed as a resource for the entire rail industry, demonstrating how private sector investment can work alongside future public sector reforms to support innovation and improve services for passengers.

She said the company remains committed to supporting the long-term development of Britain's railway through investment in new trains, infrastructure and emerging technologies.

The electrified testing loop provides a dedicated environment for evaluating modern traction systems and rolling stock performance under realistic operating conditions. It is expected to support a wide range of future projects, including battery, hybrid and alternative-fuel technologies as the railway continues its transition towards decarbonisation.

Long Marston has already played a key role in rail innovation through the development and testing of HydroFLEX, the UK's first hydrogen-powered passenger train. Porterbrook has invested more than £14 million in the pioneering project as part of wider efforts to explore alternative traction technologies.

The company has also strengthened its position within the rail supply chain through investments such as its 49 per cent stake in Scottish engineering specialist Brodie Engineering.

Alongside the opening of the new test facility, Porterbrook unveiled refreshed corporate branding reflecting its evolving role within the rail industry. The company said the rebrand underlines its commitment to collaboration, innovation and long-term investment across the sector.

The opening of the electrified test loop is expected to enhance the UK's capability to develop, test and commercialise new rail technologies domestically, reducing reliance on overseas facilities and helping accelerate innovation across the national railway network.

As the industry continues to modernise and prepare for the transition to Great British Railways, facilities such as Long Marston are likely to play an increasingly important role in shaping the future of rail transport in Britain.
