Norfolk and Western Class J is a class of 4-4-2 steam locomotives purchased by Norfolk and Western Railroad, this being the second "J" class, and should not be confused with the later, 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]
