Three Bridges Traincare Facility

Stabling and maintaining the new, state-of-the-art Class 700 fleet

A new purpose built train care facility in West Sussex

The purpose-built Three Bridges train care facility in Crawley, West Sussex, was completed in summer 2015 and is one of two new maintenance depots for the GTR Thameslink route. Together, the two new depots at Three Bridges and Hornsey stable and maintain the state-of-the-art Class 700 fleet with the Hornsey depot able to take six other class of trains as well for use on Great Northern and Thameslink routes.

The new facility was built and commissioned minimising disruption to the existing live operational depot and mainline services.
