GTW 6224 & IANR 3804 Lead CN L521 In Joliet, IL 6/9/26

This video was recorded on 6/9/26. Lots of confusion about this train. Everyone was saying this was a late L515 while me and a few others thought it was L521. Went to Joliet just to confirm and see the yard when they got the line up. Very cool duo on this local train. #train #railfan #railroad #canadiannational #railway #railtrack #grandtrunkroad #iowanorthern
