Led by two Dash-9s, NS Train #375 rumbles across the old Big Four's Wabash River bridge at Carol, IN, with 20 loaded limestone cars. Constructed by a subsidary of the Cleveland, Cincinnati, Chicago and St. Louis Railway circa 1910 as part of the branch between Mt. Carmel, IL, and Evansville, IN, the Warren Truss bridge now serves Norfolk Southern carrying unit coal and limestone trains bound for Duke Energy's Gibson Generating station.
