71000 and 70013, two magnificently restored steam locomotives from the 1950's. The Duke of Gloucester No 71000 was originally scrapped after first being picked for preservation in the National Collection, however, it was decided that only the valve gear arrangement was of real historic interest so they removed one of the cylinders for The Collection and replaced it with a similar one and from there it languished with hundreds of others awaiting the cutters torch for 13 years in Dai Woodhams Barry Scrapyard until it was spotted and rescued by a bunch of loyal enthusiasts who formed the Duke of Gloucester Steam Locomotive Trust. Restoration began in earnest, though with many components missing, the
most expensive of which being the Caprotti valve gear, it took another 13 years
of effort to return the locomotive to near as-built
condition. This particular class of engine went on to be one of the most efficient and powerful locomotives of the time.
What made this locomotive special was the fact that out of a proposed batch of several dozen only one was ever produced - for many reasons both technical and political.
the other locomotive 70013 Oliver Cromwell was built in 1951 and allocated to Lincoln where it ran daily 500 mile return trips hauling fast passenger freight from London to Norwich and Lincoln. At the end of steam it was taken into the National Collection and restored to as new condition.
