The UK’s only continuous test loop
With a substantial pipeline of new build train orders needed to replace ageing fleets, Long Marston will play a pivotal role in supporting the delivery of the next generation of electric and multi-mode fleets to the UK railway. The site’s brand new 3.5km electrified test track allows commissioning of trains in the safety of a closed secure environment, freeing up capacity on the mainline.


The track, which is the UK’s only continuous test loop, allows trains to test at speeds of up to 50mph around the outer loop and is suitable for 25kV static and dynamic testing.
Access to 24-hour security, high-quality facilities, close collaboration with local suppliers and operational staff on hand means a full turnkey solution tailored to your needs.
