Wisconsin Steel 21 6-19-76

Wisconsin Steel Porter 55T 21 (8274 10/50) ex USS Clairton Works 20 nee Carnegie-Illinois 20 @Chicago IL 6-19-76. Although I passed the Wisconsin Steel works on almost every trip I took to Chicago, my photos of their locos are very few because on heavy traffic on Torrance Av, distance from road, obstructions and mill security.
