A Mona, IA, to Chicago, IL, ethanol train begins the twist and turns working down the Monona Hill from MP 11. Here they bend around one of the many curves as they past one of the farmstead tuck away in the valley. 4 SD40's power this 80 car train, which is needed to get the train up Calmar Hill, and usually after Calmar the crew will setout one motor for the rest of the trip to Chicago. Today they will do it at Marquette. Photo: private property with permission.
