Nashville, Chattanooga & St. Louis 2-10-0 "Decapod" Type Locomotives

Class P1-51 (Locobase 8332)

Data from NC&StL 6 - 1951 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Part of the 200-locomotive residue of an order of Decapods for the 5-foot gauge railways in Russia, these 5 served the N, C & St L on its Paducah, Ky and Huntsville, Ala branches for years. Notice the low average axle loading.
