Chicago Union Station

Chicago Union Station is an intercity and commuter rail terminal located in the West Loop Gate neighborhood of Chicago, Illinois. The station is Amtrak's flagship station in the Midwest. While serving long-distance passenger trains, it is also the downtown terminus for six Metra commuter lines. The station is just west of the Chicago River between West Adams Street and West Jackson Boulevard, adjacent to the Chicago Loop. Including approach and storage tracks, it covers about nine and a half city blocks .

The present Chicago Union Station opened in 1925, replacing an earlier station on this site built in 1881. The station is the fourth-busiest rail terminal in the United States, after Pennsylvania Station, Grand Central Terminal, and Jamaica station in New York City. It is Amtrak's overall fourth-busiest station, and the busiest outside of its Northeast Corridor. It handles about 140,000 passengers on an average weekday and is one of Chicago's most iconic structures, reflecting the city's strong architectural heritage and historic achievements. It has Bedford limestone Beaux-Arts facades, massive Corinthian columns, marble floors, and a Great Hall, all highlighted by brass lamps.
