Initially allocated to Parkeston Quay in 1956, this locomotive remained on the Eastern Region of British Railways until 1966 and then transferred to the Southern Region. D2554 was from the first batch of class 05 locomotives which were built with cabs only 11ft (3.35m) high, making it suitable to fit the restricted loading gauge of the Isle of Wight railways. Arriving at Ryde Shed in 1966 she was used to haul engineering trains during the electrification of the Ryde Pier Head to Shanklin line and for maintenance trains thereafter. The locomotive was christened ‘Nuclear Fred’ by the Islands railway staff, a name that has followed to the Steam Railway to which it was transferred on 23 August 1984. ‘Nuclear Fred’ is in full working order although lack of train air brake equipment confines it to works train and demonstration goods train duties. She is usually on display on display in our Train Story Discovery Centre.
