April 23, 1917) Penn Central Transportation Company (former services of the New York Central Railroad and Michigan Central Railroad) (moved from LaSalle Street Station October 27, 1968) Amtrak (began May 1, 1971, moved from Dearborn Station May 2, 1971 and Central Station March 6, 1972 (Floridian moved January 23, 1972); Amtrak's Calumet and Indiana Connection commuter trains also ran into Union Station) 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
