It is presently operated by Hitachi as part of their contract to maintain the AT300 units for London North Eastern Railway and TransPennine Express.
[9] The shed (then Doncaster Carr Motive Power Depot) was partially reconstructed in the mid 1950s, and the roof replaced.
[15] In 2009 Hitachi became preferred bidder for the Intercity Express Programme (IEP); a program aiming to procurement mainline high-speed intercity trainsets from the Hitachi A-train family; in 2012 contracts were signed for the first phase of the project, for trains for the Great Western Main Line (GWML), with agreement reached on a second phase for replacement trains for the East Coast Main Line (ECML) – as part of the contract Hitachi was required to build a maintenance depot at Doncaster.
[19][20] Initial specifications were for a 4 road maintenance shed, for 10 car (262 metres [860 ft]) trains, with an additional single road shed for maintaining separate diesel power cars,[note 3] and facilities for re-fuelling, wheel re-profiling, washing, and toilet emptying, as well as overnight stabling facilities (sidings for 4 full and 20 half trainsets) and staff and warehousing.
[23][24][25] The 2012 plans removed the separate power car maintenance shed,[note 3] removed some cleaning facilities, and reduced the siding layout to a capacity of 20 five car (half train) sets due to changes in expected train timetabling, reducing the site's overall area.
[26] The 2013 plans re-instated a bio-cleaning pit, extended the train wash, and added an additional mainline track connection south of the main maintenance shed.
