The Union Station of Louisville, Kentucky is a historic railroad station that is serving as offices for the Transit Authority of River City, as it has since mid-April 1980, after receiving a year-long restoration costing approximately $2 million. It was one of two union stations in Kentucky, the other being in Owensboro. It superseded previous, smaller, railroad depots located in Louisville, most notably one located at Tenth and Maple in 1868-1869, and another L&N station built in 1858. The station was formally opened on September 7 1891 by the Louisville and Nashville Railroad. It was stated to be the largest railroad station in the Southern United States, covering forty acres (16 ha).
