Union Station

Chicago's Union Station stands as a monument to the city's status as a national railroad hub. The entire station sprawls a whopping ten city blocks, with 24 different rail lines approaching the facility. The roar of engines and the piercing whistle of the locomotive can be heard for miles around.

The station's Great Hall is a soaring, domed interior plaza crowned with a 115-foot high, barrel-vaulted, glass skylight. Sunshine floods the hall with light and warmth. Passengers' footsteps click-clack across the marble floors, echoing off the slender Corinthian columns the line the Great Hall on all sides. A massive staircase leads from the Great Hall onto the various train concourses.

Thousands of commuters and tourists flood Union Station daily, making it one of the most visited places in Chicago.
