Three of the Santa Fe’s twenty relatively uncommon SD39’s lead a westbound coal train past a classic windmill in Watrous, new Mexico. It appeared that the SD39’s were assigned to the Raton Subdivision at this time. As a class, the SD39’s were the filthiest locomotives that I ever observed on the Santa Fe.
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.
