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 (including 10,000 Amtrak passengers) 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.
