LNER Class A4
The Class A4 is a class of streamlined 4-6-2 steam locomotive designed by Nigel Gresley for the London and North Eastern Railway in 1935. Their streamlined design gave them high-speed capability as well as making them instantly recognisable, and one of the class, 4468 "Mallard", holds the world record as the fastest steam locomotive. Thirty-five of the class were built to haul express passenger trains on the East Coast Main Line route from London Kings Cross via York to Newcastle, and later via Newcastle to Edinburgh, Scotland. They remained in service on the East Coast Main Line until the early 1960s when they were replaced by Deltic diesel locomotives. Several A4s saw out their remaining days until 1966 in Scotland, particularly on the Aberdeen - Glasgow express trains, for which they were used to improve the timing from 3.5 to 3 hours.
Norfolk and Western 1218
Norfolk and Western No. 1218 is a steam locomotive that at one time was the strongest-pulling operational steam locomotive in the world. It is a four-cylinder simple articulated locomotive with a 2-6-6-4 (Whyte system) wheel arrangement. The Norfolk & Western Railway built it in 1943 at its Roanoke Shops in Roanoke, Virginia, and was part of the Norfolk & Western's class A fleet of fast freight locomotives. It was retired from regular revenue service in 1959, but Norfolk & Western successor Norfolk Southern Railway operated it in excursion service from 1987 to 1991. Today it is on display at the Virginia Museum of Transportation in Roanoke.
