The Huron, SD, to Chicago Clearing Yard, IL, freight train rolls thru the small town of Ft. Atkinson at MP 48. The next 5 miles will be a full plate for these 3 SD40's and the 10,000 tons of freight to get up the 1.4% Calmar Hill. The engineer is about to come out of dynamics and go after them here in less than a mile.
