With the sun set and dynamic brakes howling, the Spencer, IA, to Mason City, IA, drops down into the river valley at Algona. The train is a few miles west of Hobarton with 23 AGP loads out of Emmetsburg, IA, and 80 ethanol loads out of Hartley, IA. This is B40's crew and they went to work at 17:30 at Emmetsburg for the 75 miles trip to Mason City.
