What city is this majestic railway station located in?

Washington Union Station is a major train station, transportation hub, and leisure destination in Washington, D.C. Opened in 1907, it is Amtrak's headquarters and the railroad's second-busiest station with annual ridership of just under 5 million and the ninth-busiest in overall passengers served in the United States. Daniel Burnham, a famed Chicago architect wrote; "The station and its surroundings should be treated in a monumental manner, as they will become the vestibule of the city of Washington, and as they will be in close proximity to the Capitol itself."
