Hitachi Newton Aycliffe (also known as Newton Aycliffe Manufacturing Facility) is a railway rolling stock assembly plant owned by Hitachi Rail Europe, situated in Newton Aycliffe, County Durham, in the North East of England. Construction started in 2013 at a cost of £82 million, with train assembly commencing in 2015. It was the first factory that Hitachi built in Europe, as a result of it winning the Intercity Express Programme tender.Originally on opening, no actual manufacturing operations took place at the site; it assembled components built elsewhere into completed trains. However, for the later classes, some manufacturing took place on site. By October 2017, the plant employed over 1,000 members of staff.
