A Canadian National freight rumbles over the Pembina River Bridge between Entwistle and Evansburg, Alberta, on CN’s Edson Subdivision toward the end of the day on August 4, 2016. Powering the train are two CN EMD SD75Is, Nos. 5686 and 5709.
The EMD SD (special duty) series are a strong and reliable kind of locomotive which still serve America's rails today. They have proved themselves reliable by clocking in several million miles of freight service over several decades.
