Class of British 4-6-2 locomotives From Wikipedia, the free encyclopedia
London and North Eastern Railway's (LNER) Peppercorn Class A1 is a class of 4-6-2 "Pacific" steam locomotives largely built between 1948 and 1949 at Doncaster and Darlington Works to a design of Arthur Peppercorn. Forty-nine were built for hauling express passenger services on the East Coast Main Line owned by LNER's successor, British Railways' North Eastern Region. None of the original 49 Peppercorn A1s survived into preservation, with the last being scrapped in 1966. The 50th Peppercorn A1, 60163 Tornado, was completed in 2008 as an evolved member of its class.

Most of the former LNER Class A1 locomotives designed by Sir Nigel Gresley had been rebuilt as LNER Class A3 locomotives prior to this class being conceived. The few straggling LNER Class A1 locomotives that remained unrebuilt during the tenure of Peppercorn's predecessor, Edward Thompson, were redesignated by him as Class A10s in preparation for the construction of his new Class A1 locomotives. Thompson rebuilt the pioneer LNER Pacific Great Northern in 1945; originally this was the new Class A1, but the rebuild was not repeated. Instead, initiated by Thompson but largely taken forward by his successor Arthur Peppercorn, Great Northern was designated Class A1/1, and a new class of Peppercorn A1s ordered.
The locomotives were designed to cope with the heaviest passenger trains in the post-war period on the East Coast Main Line (London – York – Newcastle – Edinburgh – Aberdeen) which consisted normally of trains with up to 15 coaches and up to 550 tons. The Peppercorn A1s were able to pull such a train on the flat at a speed of 60–70 mph (95-110 km/h). The class used a double Kylchap chimney system and, like previous LNER Pacifics, had a 3-cylinder arrangement.
The new A1s were ordered by the LNER but were delivered after the LNER had been nationalised to form part of British Railways at the start of 1948. The 49 engines were built at the Eastern Region's Doncaster and Darlington works between 1948 and 1949.
By summer of 1966, all 49 class members had gone for scrap. The last to be withdrawn from stock was No. 60145 Saint Mungo, after a working life of just 17 years. 60145 Saint Mungo was planned to be preserved by Geoff Drury; however, this ultimately was unsuccessful and none of the original locomotives were preserved.

The names of the A1s[10] were an eclectic mix including:
None of the original production run of 49 Peppercorn A1s survived the scrapyard to be preserved. However, in 2008, a brand new 50th A1 based on the original Peppercorn patterns, 60163 Tornado, was completed as the evolved member of the class.[11]
Bachmann Branchline and Hornby make models in OO gauge, Graham Farish produce a model in N gauge and Accucraft (UK) make a live steam model in Gauge 1.
