Under a new 1852 charter, the Beloit & Madison Railroad Company was organized.

The evidence

• “The partially graded line on a direct route between Janesville and Madison was abandoned. In 1852 a new charter had been obtained, and the " Beloit & Madison Railroad Company " had been organized to build a road from Beloit via Janesville to Madison. A subsequent amendment to this charter had left out Janesville as a point, and the Beloit branch was pushed through to Madison, reaching that city in 1864.”
