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.
The Brownville Bridge was built over the Missouri River in 1939. Today it is on the National Register of Historic Places. Owing to its place in Nebraska history, Brownville is primarily a tourist attraction with several old houses opened for tours or converted into museums. Art galleries and wineries in and near Brownville have also helped to make the town an increasingly attractive getaway for residents of the region's larger cities. Omaha's River City Star was built in the town in 1967, and was originally named the Belle of Brownville. The Governor Furnas Arboretum was planted in the city in 1992. The arboretum is named in honor of Nebraska's second governor, Robert W. Furnas, the signer of the first declaration of Arbor Day. The Cooper Nuclear Station is south of the city. In 1995 a mild tornado blew through the town.
