Norfolk and Western Class J of 1903 or the Second J Class was a class of 4-4-2 steam locomotives purchased by Norfolk and Western Railway. They were before the more well known J class of 1941. The retirement of the first J classes in 1900 left the designation available for reuse for these engines. There were 7 of these Class Js made, and they were retired between 1931 and 1935, once again leaving the "J" class designation available to be reused in 1941.[1]
