The story
The Galena and Southern Wisconsin Railroad was incorporated on January 26, 1853, in Illinois, and on March 2, 1857, in Wisconsin. After obtaining financing, construction work began in 1872 on a 3 ft (914 mm) line. The line was completely open between Galena, Illinois, and Platteville, Wisconsin, on January 1, 1875. Also serving Platteville was the Dubuque, Platteville and Milwaukee Railroad (a forerunner of the Milwaukee Road), which had opened in 1870. In 1877, the company extended its line further north toward–but short of–Montfort, Wisconsin. The line branched from the original line at Ipswich, Wisconsin, four miles east of Platteville.
In 1879 the company was reorganized as the Galena and Wisconsin Railroad. Separate companies of that name were incorporated in Illinois and Wisconsin, each owning the property of the original company in those respective states. The two companies were then consolidated into a single company, again with the same name. The Galena and Wisconsin Railroad undertook no new construction before being consolidated with the Chicago and Tomah Railroad on August 31, 1880.
