The original 49 Peppercorn Class A1s were ordered by the LNER and built at Doncaster and Darlington for British Railways (BR) in 1948/9, after the nationalisation of the railways. As designed they were ideally suited for the post-war world of poor maintenance and heavy trains, with their 50sq ft grate allowing them to use lower grade coal than their predecessors, this engine was built from scratch using the original plans, and I was lucky enough to see it when it came into Newcastle upon Tyne recently.
