The Milton–Janesville branch of the Milwaukee & Mississippi Railroad was opened for traffic.

The evidence

• “The first railway to enter Janesville was constructed by the corporation now known as the Chicago, Milwaukee & St. Paul Company and was built from Milton to Janesville, occupying the line of the Southern Wisconsin Railway Company, and was opened about January 1, 1853. As an inducement for obtaining the road a few of the citizens of Janesville raised a bonus in cash, which was paid to the company constructing the road.”
