The Sheboygan and Mississippi Railroad, incorporated in 1852, had completed a line from Sheboygan, Wisconsin, to Glenbeulah, Wisconsin, by 1860. This line had no connections to other railroads; goods were shipped out from the port in Sheboygan, on Lake Michigan.[1] That company failed and was sold to the new Sheboygan and Fond du Lac Railroad, which was incorporated on March 2, 1861.[2]
The company's line ran 78.40 miles (126.17 km) from Sheboygan to Princeton via Fond du Lac.[4] The Princeton and North Western Railway extended it a further 85 miles (137 km) to Marshfield, Wisconsin, in 1901.[5] Under the Chicago and North Western Railway, the line between Plymouth and Fond du Lac was abandoned in 1952.[6] The line west of Fond du Lac, known as the Marshline Subdivision, was abandoned in stages between 1975–1985.[7] The Sheboygan Falls Subdivision, between Plymouth and Sheboygan, is the only remaining extant line.
