Coordinated efforts with County officials led to the acquisition of an abandoned rail line that has since been reactivated as the County-owned Hoosier Southern Rail Road. Managed by the Perry County Port Authority, the short-line rail road connects the Perry County River Port with the Norfolk Southern Rail Road.
Perry County was formed on November 1, 1814 (two years before the State of Indiana was admitted to the Union) from Warrick County. It was named for Commodore Oliver Hazard Perry who defeated the British squadron in the decisive Battle of Lake Erie in 1813. The Ohio River made Perry County a focal point and settlers were drawn here due to plentiful supplies of natural resources and the area's scenic beauty.
