title: Chicago and North Western J Class
text: # Chicago and North Western J Class
  
  The Chicago and North Western Railway class J was a class of 310 American 2-8-2 locomotives. They were built between 1913 and 1923 by the American Locomotive Company. In addition, the Chicago, St. Paul, Minneapolis and Omaha Railway (the Omaha Road) acquired 32, and also classified them as class J.
  
  ## Design
  
  The locomotives had boiler pressed to 185 pounds per square inch (1.28 MPa) feeding steam to two cylinders that had a 27-inch (690 mm) bore and a 32-inch (810 mm) stroke. These were connected to 61-inch (1,500 mm) driving wheels. The locomotives weighed 467,500 pounds (212,100 kg).
  
  The first 224 locomotives, built 1913 to 1919 had Baker valve gear, the last 118, built 1921 to 1923 had Young valve gear.
  
  ## Construction
  
  The locomotives were built by the American Locomotive Company at their Schenectady, Richmond, and Dunkirk, plants.

  ## Service
  
  They were used system-wide on freight trains, and became the principle freight-hauling locomotive on the railway.
  
  The last seven locomotives built were equipped for oil firing from new; at least 18 more were retro-fitted in the 1930s and 1940s. These locomotives were used in Nebraska and Wyoming.
  
  When new, the locomotives were hand-fired; in the mid to late 1930s many were rebuilt: driver diameter was increased by 3 inches (76 mm), boiler pressure was increased to 200 pounds per square inch (1,400 kPa) to compensate, and a BK stoker was fitted. These locomotives were reclassified as J-A. With the onset of World War II, rebuildings ceased, but the fitting of stokers continued; these stoker-fitted locomotives were re-classed as J-S.
  
  Also during the war, several locomotives were leased to the Seaboard Air Line Railroad.
  
  In 1944 the Chicago and North Western Railway traded two of its class J locomotives for the Omaha Road's two J-1 2-10-2 locomotives.
  
  Retirements started in 1942, and continued until the end of steam in 1956.
