Chicago, St. Paul, Minneapolis & Omaha 2-10-2 "Santafe" Locomotives in the USA

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.
