Millennium Station (formerly Randolph Street Terminal; sometimes called Randolph Street station or Randolph/South Water Street station) is a major commuter rail terminal in the Loop (downtown), Chicago. It is the northern terminus of the Metra Electric District to Chicago's southern suburbs, and the western terminus of the South Shore Line to Gary and South Bend, Indiana. Located under Millennium Park, the terminal is a stub-end station and was established in the 1800s by the Illinois Central Railroad (IC) and has gone through several re-configurations. Most recently, it was rebuilt in the early 21st century and is owned by Metra through its operating arm, the Northeast Illinois Regional Commuter Railroad Corporation. Not counting commuters on the South Shore Line, over 18,000 people board Metra trains at Millennium Station each day. During peak periods, trains leave the terminal as frequently as twice a minute. It is the third-busiest train station in Chicago. History As Great Central Station, Randolph Street Terminal, along with Van Buren Street a few blocks south, was IC's primary downtown Chicago terminal until the completion in 1893 of Central Station (closed 1972) just south of Grant Park at today's Roosevelt Road. It still received many trains thereafter, but was of secondary importance. Its importance increased dramatically in 1926 with the electrification of commuter services on IC's main line and its Blue Island and South Chicago branches. Commuter trains from all three branches were now routed into the Randolph Street terminal, while intercity traffic continued to terminate at Central Station. For many years, the station platforms were exposed and the ticketing facilities and the waiting room were located in the attached facility. The construction of Millennium Park gradually placed the entire station "underground." Randolph Street Station existed in a state of perpetual construction from the mid-1980s until 2005: exposed steel girders covered in flame retardant, unpainted plywood walls, bare concrete floors, and dim utility lights created a notoriously unfriendly, cave-like environment. Skidmore, Owings and Merrill was the architect for the station redesign. With the completion of construction in 2005, the station was renamed Millennium Station. However, many longtime Chicago-area residents still call it "Randolph Street Terminal." Station layout The main entrance to the station is at the southwest corner of the intersection of Randolph Street and Michigan Avenue. From the entrance, a concourse lined with shops and restaurants leads to the main waiting area. The waiting area consists of a
