Louisville & Nashville Class K-5 and K-7 4-6-2 "Pacific" Steam Locomotives

The L&N K-5 and K-7 classes were both 4-6-2 Pacific-types. Three of these locomotives were streamlined for express passenger service; two of the class K-5 (Nos. 275 and 277), and K-7 class No. 295. No. 295 was originally a 3-cylinder locomotive built by Alco-Brooks. It was rebuilt to 2 cylinder and streamlined by the L&N's South Louisville Shops for use on the South Wind. The locomotive was similar in appearance to the Southern Pacific's full skyline casing and had a protruding nose cone that contained the headlight. No. 295 had some of the streamlined casing removed in 1952.
