A worker at Union Pacific’s Downing B. Jenks Shop at North Little Rock, Arkansas, makes a thorough inspection of an EMD SD70M, writing up any defects and other work that needs to be done before the locomotive heads into the shop for repairs on May 19, 2015.
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.
