Norfolk and Western Railway`s J class steam locomotives were a class of 4-8-4 locomotives built by the Norfolk and Western Railway`s East End Shops in Roanoke, Virginia, between 1941 and 1950 Norfolk and Western Railway. The first batch, numbered 600 to 604, were built in 1941–42 and were delivered streamlined. In 1943, 605–610 were delivered without shrouding and lightweight side rods, due to the limitations on the use of certain materials during the war; due to these distinctions, they were classified J1. But, when N&W showed the War Production Board the reduced availability numbers because of this, the Board allowed the J1s to be re-fitted as Js with the lightweight rods and shrouding in 1944. The last batch, 611–613, were built in 1950, all streamlined. The Js were built and designed completely by N&W employees, something that was uncommon on American railroads. The class should not be confused with the much earlier J class of 1903. The total cost for building 611 was $251,544 in 1950.
