Burlington Northern SD40-2 on Marias Pass

 

This Burlington Northern SD40-2 begins the ascent of Marias Pass at Two Medicine Bridge. A heavy lumber train rolls down the track enroute from Seattle headed to Chicago. The carloads thunder through the mountains and over the Flathead River, echoing through the Rockies. The audible groan of locomotives 6818 and 6820 shoving on the rear sounds in the distance as the train continues on its way.
