High Quality Content by WIKIPEDIA articles! There were a number of engine sheds and railway works located in York and this entry covers all of those establishments. This approach has been taken due to the close operational relationship (and geographical proximity) of these establishments, so collecting all this information in a single entry, rather than series of separate entries seemed more logical. Information on some sheds is more detailed and better documented than some of the early, short-lived establishments. The large York North engine shed became the National Railway Museum in 1975.
