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.
