The Norfolk and Western K2 and K2a classes were 4-8-2 "Mountain" steam locomotives built for the Norfolk and Western Railway (N&W).

History

Ten K2s were built by American Locomotive Company (ALCO) in 1919 as part of the United States Railroad Administration (USRA) Heavy Mountain design. After being released from the USRA control, N&W ordered twelve similar-looking 4-8-2s from Baldwin Locomotive Works (BLW) in 1923. These new locomotives had incorporated parts design from the N&W, larger smokestack, and exhaust stand, which classified them as K2a.

In the late 1940, these locomotives were rebuilt and streamlined in a similar fashion to that of the J class of 1941, earning them the nickname J Juniors. They also were fitted with roller bearings on all but the drivers, new fireboxes and strokers, and new cylinders. They were eventually retired and scrapped between 1957-1959 with none preserved.^[3]
