Union Station (originally Union Depot), also known as Atlantic Coast Line Railroad and Southern Railway Station, is a historic train station located at Columbia, South Carolina. It was built in 1902, and is a brick and stone, eclectic Jacobethan Revival / Tudor Revival building. It features stepped gables and towering chimneys. It was designed by architect Frank Pierce Milburn for the Atlantic Coast Line Railroad and Southern Railway. In contrast to the custom of ‘union station’ denoting the single station for several railroads, the Seaboard Air Line Railroad had its own station one-half mile away. The formerly Seaboard Silver Star still operates through another station in Columbia.
Until the 1950s and 1960s the station served several named trains. In contrast to the New York — Florida trajectories of the Amtrak trains today passing through Columbia, the trains offered service in different directions as well.
