| UP 1780, a six month old SD40N idles at the Davidson Yard ready tracks after being serviced in the diesel shop. Delivered to Chicago & North Western as CNW 6809 SD40-2 in August 1973, this unit would keep this number until the Union Pacific merger becoming UP 2958 on October 1, 1998. Fourteen years and six months after entering the UP roster this SD40-2 was released from North Little Rock as SD40N 1780 looking like a brand new locomotive. Note the ATC/ATS shoe on the rear truck required for service on the former C&NW lines with Automatic Train Stop and Automatic Train Control. |
