York Historic Environment Record

The york central audit of heritage assets report mentions that the carriage works office was constructed between 1875 and 1888.

Following the creation of the North Eastern Railway, the Company gradually rationalised its many workshops concentrating locomotive construction and major repairs at Darlington, wagon-building at Shildon and Darlington, and carriage-building and major repairs at York.
In the later years of British Rail, York became one of very few major train-building workshops left in Britain, and constructed vehicles for export as well as the home market. However, it was fundamentally reliant on home orders, and a three-year moratorium on these in the run-up to BR privatisation led the owners, ABB Rail Vehicles, to decide on closure in 1995.
