Like many regional lines, the Iowa Interstate Railroad used to exclusively use   
   old locomotives, SD40-2 and such, but has now purchased new GE Evolution   
   series units. Two of these have enough horsepower to move their longer trains,   
   but not enough tractive    
   effort for the steepest part of the route. The railroad therefore puts one of   
   their old units into the consist for extra pulling power. This would seem to   
   be a logical application for traction slugs, and in fact the Iowa Interstate   
   has several slugs in    
   their fleet, but these are D.C. units paired with older locomotives. Has any   
   railroad yet put into use traction slugs that are powered from A.C.   
   locomotives?
