Loco 71000 'Duke of Gloucester' was perceived as a modified Princess Coronation (Duchess) with four cylinders and a double blast pipe. It was also to have had bar frames. However, a terrible accident at Harrow and Wealdstone in October 1952 completely wrecked the ex London Midland & Scottish Railway Pacific 46202 'Princess Anne' which had only entered traffic two month before after being rebuilt from 46202 Turbomotive. The accident left a gap in the ranks of the ex LMS Pacific stud and therefore Robert A. Riddles, an executive at Crewe Works, took the opportunity to introduce the leader of the proposed new class of BR Standard Class 8 Pacifics.

To gain running experience, only one was built until such time that orders could be placed for a quantity and quality construction. Riddles did however, obtain authorisation to proceed as it was not part of the agreed building plan. Unfortunately, it was to remain the only example built.

Originally scheduled for official BR preservation, only part of the engine was officially preserved i.e. the left hand cylinder and valve gear was removed and can be seen at the Science Museum in London.

This prototype locomotive was withdrawn from Crewe North Shed, where it spent all its life, in November 1962. It was bought for preservation in 1972 after spending twelve years in open storage, seven of them at Woodham Brother's scrapyard at Barry, South Wales where it had arrived sometime in 1966. When rescued from the scrapyard it was taken to Loughborough to begin a pioneering 16 year restoration programme.

The magnificent condition of the locomotive today contrasts sharply with the forlone scrapyard condition of 1972. It is now a regular performer on main line specials.

The loco 71000 was withdrawn on 24 November 1962 from Crewe North shed.

Locos 71000 is preserved.
