   The solution at newly-installed floor-height platforms on Chicago South   
   Shore and South Bend Railroad put freight on the tangent and commuter   
   trains on the gauntlet, with the platform well outside clearance required   
   for wide loads. Both mains clear wide loads in double-track territory.   
      
   I'll agree with hancock on this one.
