         The spring thaw is underway and Alco RS-27 (model DL640) sits in a
        slushy Wisconsin Rapids yard.
  
        Compare this photo to a 1960 builder's photo
        and note the changes: 
        
          - The large glass all-weather windows have been replaced by a much
            smaller one.
 
          - The steps on the end of the loco have been replaced with Alco
            Centruy-style ladders.
 
         
        These changes occurred about about 1965-66.
