 10000, which became known as the "hush-hush" due to the secrecy surrounding its construction, was also stabled at Gateshead before being converted into a more conventional locomotive.In BR days, the shed continued to house mainly ex-NER/LNER locomotives, the BR standard classes being somewhat conspicuous by their absence from north east lines (one exception being a modified batch of the massive "9Fs" which had been specially fitted with large Westinghouse air pumps; these locomotives were stabled at Tyne Dock shed and employed on the heavy iron ore trains to Consett Steelworks where the pumps were needed to operate the air powered doors on the large bogie ore hoppers).Gateshead also provided motive power for Dunston Staithes, to the West, which had restrictions in place regarding locomotives that could work on them, these being, in LNER and BR days, J71 and J72 0-6-0 tanks and a pair of Y3 sentinel geared locomotives affectionately known as "pups".
