      Locomotive #311 was Green Bay & Western's first Alco
      "Century" unit.  It was delivered in the fall of 1963 after
      display at a Chicago railroad show.  This is an early version of the
      C-424 locomotive with intercooler access side panels and projecting rear
      number boards.  It was the first of four such units purchased by the
      railroad over the next two years.  These locomotives were the
      mainstay of the Green Bay Route's power during the next twenty
      years.  The units were typically run in groups of three
      on the trans-Wisconsin time freights. 
      GB&W's FA-1 #507 was traded in to Alco as part of the
      purchase.  The Green Bay Route was able to save about a third on the
      cost of the new engine by dismantling the FA-1 in their own shops. 
      Number 311 holds a place of honor among Green Bay Route locos -- it
      hauled the last train ever on Saturday August 28, 1993.  It was then
      sold to Minnesota Commercial Railroad where it worked as #311
      until it was wrecked in 1996. 
      It is interesting to note that the builders photo does not show the
      Scotchlite checkerboard striping along the running board, nor a Green Bay
      Route herald on the nose. Since it was a display unit for Alco, the
      company wanted a clean appearance for the loco so they left the front
      herald and the frame stripes off so the unit. They were applied after the
      engine arrived at the Norwood Yard shops.
