Railroad, and the North Western Limited, operated by the Chicago and North Western Railway. The North Western Limited was discontinued on June 14, 1959, and the last runs of the Black Hawk were on April 12, 1970. The Pioneer Limited was thus the last privately operated overnight passenger train on the route. For a time in the 1970s and early 1980s, Amtrak operated overnight rail passenger service along the route of the Pioneer Limited, as part of longer-distance routes from Chicago to either Seattle or Duluth. The last such trains departed on October 25, 1981, but the route still has a day train. References Dubin, Arthur D. Some Classic Trains. Milwaukee: Kalmbach Publishing Co., 1964. .
