Union Station in Atlanta was the smaller of two principal train stations in downtown, Terminal Station being the other. Opening in 1930, Union Station served the Georgia Railroad, Atlantic Coast Line (previously the Atlanta, Birmingham and Coast Railroad), and Louisville and Nashville (previously the Nashville, Chattanooga and St. Louis Railway). It replaced earlier stations on the same site.
After the tenant railroads of Union Station had discontinued all their passenger trains -- the last such train operated the day before Amtrak came into existence -- the station was razed in 1972. Remnants of the platform may be seen behind the Atlanta Journal Constitution building although construction of Underground Atlanta and MARTA largely obliterated the site.
