Chicago Union Station


Chicago Union Station is an intercity and commuter rail terminal located in the West Loop neighborhood of the Near West Side of Chicago, United States. Amtrak's flagship station in the Midwest, Union Station is the terminus of eight national long-distance routes and eight regional corridor routes. Six Metra commuter lines also terminate here.
Union 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 station opened in 1925, replacing an earlier union station on this site built in 1881. The station is the fourth-busiest rail station in the United States, after Pennsylvania Station, Grand Central Terminal, and Jamaica station in New York City, and the busiest outside of the Northeast Corridor. It handles about 140,000 passengers on an average weekday. It has Bedford limestone Beaux-Arts facades, and an interior with massive Corinthian columns, marble floors, and a Great Hall, highlighted by brass lamps.
The station connects to multiple transit authorities including the Chicago Transit Authority bus and Chicago L lines, Metra, Pace, Greyhound, and more either within the station or within walking distance.

Historical services

Union Station was served by lines in all directions even before Penn Central and Amtrak consolidated the downtown terminals. The station served as a terminal for the following railroads:
  • Chicago and Alton Railroad – only a tenant, later part of the Gulf, Mobile and Ohio Railroad
  • Chicago, Burlington and Quincy Railroad
  • Chicago, Milwaukee, St. Paul and Pacific Railroad – The station housed its corporate offices from 1924 to 1986
  • Pittsburgh, Fort Wayne and Chicago Railway
  • Pittsburgh, Cincinnati, Chicago and St. Louis Railroad
  • Penn Central Transportation Company
  • Amtrak
Some of these trains and their names have survived to present Amtrak services, such as the Empire Builder, the California Zephyr, and the Hiawatha.
The name Ann Rutledge was used by Amtrak as a Chicago-St. Louis-Kansas City route until a name and service consolidation in 2009. There is also a Lincoln Service that operates in Illinois.

Interior

Station building

Located west of Canal Street, Union Station's station building occupies an entire city block. At its center is the Great Hall, the main waiting room. Arrayed around the Great Hall are numerous smaller spaces containing restaurants and services, and a wide passageway leading to the concourse. Above the main floor are several floors of office space, currently used by Amtrak. Original plans called for many more floors of offices, forming a skyscraper above the Great Hall. This was never completed, although the plan has been revived in recent years.
The Burlington Room is an event space at the northwest of the Great Hall. The room features large columns, chandeliers, four French block murals of landscape scenery, and an original mirror. The space, initially a women's lounge, was restored in November 2016, after years of damage and neglect. For event uses, the space has color-changing lights and an audiovisual system.
The headhouse includes a space formerly used as a Fred Harvey restaurant. After a large fire in 1980, the space was damaged, windows on Clinton Street were destroyed, and the space was left vacant since then. In 2018, Amtrak announced plans to redevelop the space into a multi-level food hall, using funds from the sale of its parking garage. A new entrance and canopy would be installed on Clinton Street, and new windows would replace the bricked-up windows. The food hall was planned to open in the summer of 2020.
The headhouse also includes a Metropolitan Lounge, one of seven Amtrak offers in its stations. The lounge operates like an airport lounge, accessible to business- and first-class passengers, as well as other high-price ticketed passengers. The lounge reopened in June 2016, moving from the concourse to the headhouse. It has two stories and, double the space of the previous lounge. It features different seating areas intended for businesspeople, families and children, and people using phones or tablets. The space has bathrooms with showers, and an elevator.

Platforms and tracks

Union Station is laid out with a double stub-end configuration, with 10 tracks coming into the station from the north and 14 from the south. Unlike most of Amtrak's major stations, every train calling at Union Station either originates or terminates there; all passengers traveling through Chicago must change trains to reach their final destination. There are two through tracks to allow out-of-service equipment moves between the north and south side, including one with a platform to allow extra long trains to board. Between the north and south sides of the station is a passenger concourse. Passengers can walk through the concourse to get from any platform to any other without stairs or elevators. Odd-numbered platforms are on the north half of the station, and even-numbered platforms on the south half. The north tracks are used by Amtrak for the Hiawatha, the Borealis, and the Empire Builder, and by Metra for the Milwaukee District West, Milwaukee District North, and North Central Service routes. The south tracks are used for all other Amtrak services, as well as by Metra for the BNSF, Heritage Corridor and SouthWest Services. Two station management structures, one on each side of the terminal, monitor train-to-track assignments and the flow of traffic in and out of the station. Actual oversight and control of switching and signalling is accomplished by two "train director" positions, one for each side of the station, located in the Amtrak control center in the station's headhouse.
Numerous entrances provide access to Union Station's underground platform level. The main entrance is on Canal Street opposite the headhouse, but passengers can also reach the platforms directly from the headhouse via an underground passageway. Two secondary entrances are located in Riverside Plaza near the Jackson Boulevard and Adams Street bridges. The Union Station Transit Center bus terminal across Jackson Boulevard has a stairway and elevator leading to the south concourse. On Madison Street, across the street, and one block east from Ogilvie Transportation Center, are a set of entrances to the north platforms.

Architecture

Union Station was designed by D. H. Burnham & Company. The successor firm of Graham, Anderson, Probst and White completed the work. The terminal was among the first to anticipate automobile traffic; it was first designed in 1909, one year after the Model T entered production. It was designed with ticket offices, concourses, platforms, waiting and baggage rooms, and shops, all on a single level, meant to be easy to navigate. At opening, the terminal also housed a hospital, chapel, and jail cell.
The main building, a square Neoclassical structure, takes up one city block. Its architectural style contrasts with modern glass-faced buildings around it. The station has wide porticos and large colonnades on its exterior. The street-level entrances utilize Indiana limestone.
The station originally featured a large Beaux-Arts concourse building along the river, made with marble, glass, and iron. Massive steel arches held up the vaulted roof, and several stairways led passengers down to the platforms. The concourse was demolished in 1969 and replaced with an office tower.
