When I went to Chicago about a year ago and was driving on I-90, I saw this yard. On the way there, I saw a set with BNSF GP60M 167(in pure ATSF paint!)and NS SD70M 7523. On the way back, the set I saw was NS C40-9W 9007(Horsehead!)and BNSF AC4400CW 4423. Is this yard owned by NS or BNSF? I saw a lot of both in there. Also, a book I have has a pic of an ATSF B40-8W in a busy yard in Chicago, and it calls it Corwith Yard. Is this Corwith Yard, and if not, what is it called? I've been wondering this, and I'd like to know. After all, wouldn't you be curious if you unexpectedly saw long trains on an already fun-filled vacation?
