This set of SD70's has been running all around the UP in northern Illinois. I caught them at Rochelle a month back and then again this past Saturday at West Chicago yard. I couldn't pass up the opportunity while the set waiting for the track inspector to change tracks. The units are sitting just west of the EJ&E (CN) main called JB tower.
Here they are a month ago at Rochelle
