DM&E 6200 leads a train of empty Herzog GPS cars past the old Soo depot at Dresser, Wis. The train is minutes from arriving at the quarry where it’ll take on a load of trap rock for deposit on the Elbow Lake Subdivision, across the Minnesota-North Dakota border. SRG’s "wonder pole" makes a cameo in this photograph.
