These works will restrict access to the railway depot at Neville Hill east of Leeds, and so Northern developed a contingency plan for storage and maintenance of its electric multiple unit fleet that works the Airedale and Wharfedale railway lines.

[7] Even so, when the TRU is complete, the depot at Shipley will remain open to service the EMU fleet.

[13] The plans were confirmed by then rail minister, Huw Merriman, on 14 March 2024, who announced £100 million worth of government funding for the depot.

[14][15] Plans lodged with Bradford Council in October 2023 detailed the site as having a four-road shed, staff facilities, and office, storage space and a site for controlling train movements, with storage space for 40 trains.

[11] Cleaning of the interior and exterior of railway vehicles is envisaged (including a carriage wash section), and the site will have the ability to deal with controlled emission toilets (CET).
