2-10-2 "Santa Fe" Steam Locomotives in the USA

Chicago, St Paul, Minneapolis & Omaha

The Chicago, St. Paul, Minneapolis & Omaha Railway bought two "Santa Fe" type locomotives from the Baldwin Locomotive Works in 1917. These locomotives were used as helpers on the grades out of the St. Croix River Valley at Hudson, WI. They were designated as class J-1 and assigned road number 491 and 492. These 2-10-2 locomotives had 57" diameter drivers, 27" x 32" cylinders, a 205 psi boiler pressure, they exerted 72,300 pounds of tractive effort and each weighed 322,000 pounds.

There are no surviving CStPM&O 2-10-2 "Santa Fe" type locomotives.

Class Details by Steve Llanso of Sweat House Media

Class J-1 (Locobase 14578)

Data from DeGolyer, Volume 55, pp. 65+. Works numbers were 45976-45977 in July 1917.

Very few Santa Fe-arrangement locomotives were delivered with saturated boilers. Their direct heating surface areas included 79 sq ft (7.3 sq m) in the combustion chamber and 28 sq ft (2.6 sq m) of arch tubes. Fourteen-inch (381 mm) piston valves fed the cylinders

These two had a specific mission to serve as helpers on trains climbing out of the St Croix Valley in western Wisconsin.

At some point, the J-1s were superheated; see Locobase 14578.

Class J-1-superheated (Locobase 14579)

Data from C&NW 10 -1 1952 locomotive diagrams supplied by Allen Stanley in May 2005.

Delivered in 1917 with saturated boilers (Locobase 14578), these Santa Fes were later superheated.

After 1944, the pair bore the Chicago & North Western herald. Both engines lost their leading axles and operated as heavy 0-10-2 switchers after conversions in January (492) and July (491) 1944.

492 was retired in 1950 and 491 left in 1953.
