A four pack of RCPE SD40-2's lead the MRCHU up out of Rapid City, SD on a Saturday morning. The historic Alex Johnson Hotel can be seen in the distance. It was commisioned by a CNW VP that wanted to promote tourism in the Black Hills in the early 20th Century.
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.
