Chicago and North Western RR
The Chicago and North Western Railway was chartered on June 7, 1859, five days after it purchased the assets of the bankrupt Chicago, St. Paul and Fond du Lac Railroad. On February 15, 1865, it merged with the Galena and Chicago Union Railroad, which had been chartered on January 16, 1836. Since the Galena & Chicago Union started operating in December 1848, and the Fond du Lac railroad started in March 1855, the Galena and Chicago Union Railroad is considered to be the origin of the North Western railroad system.
