A March 1936 LNER Locomotive Committee report notes that there were two turntables at Norwich - one a 55-foot diameter example located at the south end of the shed (by Carrow Road) and the other with a diameter of 49 feet 8 inches being located close to Thorpe station.
Modernization of the facilities in the 1930s saw rationalisation of the works site and general (heavy) repairs ceased in 1934.
