The new depot has been built to the west of Reading station. This will free up the depot's previous location for new rail routes to increase rail transport capacity. Built with enhancements to allow for future stabling and servicing of electric trains, the new depot will provide capacity for 147 vehicles.
The depot it self is 210 meters long and 37 meters wide. The complex includes three road light maintenance ‘through' road sheds and a single road heavy maintenance shed, main stores, a workshop, plant rooms, a signalling room, a three storey production management office with 17 associated buildings and a car park.
This project also saw the first overhead wires installed for Network Rail's £895 million Great Western Electrification Programme. Two thousand meters of overhead line was installed on 211 head spans.
