The rise of the railroad was ultimately Brownville's undoing. The railroads siphoned traffic away from the Missouri River's steamboats. Brownville's attempt to secure a railroad of its own was severely botched and led to immense tax increases to pay the bonds for the failed venture. This drove most of the population away and led to the county seat being transferred to Auburn in 1885. In 1856 Thomas Weston Tipton moved to the town to serve as a minister. He later became a longtime U.S. Senator, and ran an unsuccessful campaign for Governor of Nebraska. Omaha land magnates Herman and Augustus Kountze held large holdings in the early town.
