A northbound Fox River Valley Railroad freight departs West Bend, Wisconsin, on a sunny March 25, 1990. Three of FRVR’s six-axle locomotives pull the train—the pair of EMD SD24s, Nos. 2401 and 2402, and the railroad’s sole former Southern Railway SD35 No. 2500. This portion of the FRVR route between Milwaukee (Granville) and Green Bay is now the Eisenbahn State Trail.
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.
