Norfolk and Western 1240 was a four-cylinder simple articulated 2-6-6-4 steam locomotive, built in June 1950 by the Norfolk and Western's (N&W) East End Shops in Roanoke, Virginia as part of the N&W's class "A" fleet of fast freight locomotives. It was the third member of the final batch of five class A 2-6-6-4 locomotives built with roller bearing side rods.^[2]

No. 1240 was retired from active service on the Norfolk and Western Railway when they began replacing steam locomotives with diesel locomotives but would surprisingly be fired up again in 1959 and used on the N&W's "Farewell to Steam" excursion train along with class Y6b No. 2174, when the "Farewell to Steam" excursion had ended that same year in 1959, No. 1240 was sold for scrap.
