Los Angeles Union Station is the main railroad station in Los Angeles, California, and the largest railroad passenger terminal in the Western US. Union Station is a major transportation hub for Southern California, serving almost 110,000 passengers a day. The station is the hub of the Amtrak's California regional routes, Amtrak's long distance trains, Metrolink commuter trains, several Metro Rail subway and light rail lines, buses and coach services. History: Established in 1939. Built in 1939, Union Station combines Spanish Colonial Revival architecture, Mission Revival and Streamline Moderne styles. The architecture team included John and Donald Parkinson who also designed Los Angeles City Hall and other city landmarks. Originally intended as a transcontinental terminus station for the Union Pacific, Santa Fe and Southern Pacific Railways, the station was a major hub for troop movement during World War II. The station's historic 161,000 square foot terminal was placed on the National Register of Historic Places in 1980 and the station was restored in 1992. Beginning in the 1970s, growing use of Amtrak and expansion of local and regional rail revitalized the station as a major transportation hub of Southern California. Metro acquired the station in 2011, managing the property that currently serves as a transportation hub for Metro, Metrolink, Amtrak and other transportation services as well an urban mixed-use development site.
