Iowa Hogbacks
The main reason for my visit to the CN Dubuque Sub in northeastern Iowa was to see the topography of the line first hand. Much of the line between Waterloo and Manchester follows the contour of the rolling fields and hills common in this portion of the state. Eastbound Waterloo to Kirk Yard train M338 prepares to descend one of the many hogbacks found on this line as it approaches a crossing between the small towns of Raymond and Jesup.
