The Richard B. Ogilvie Transportation Center (; formerly Chicago and North Western Terminal) is a commuter rail terminal in downtown Chicago, Illinois. It is the terminus for the three commuter rail lines of Metra's Union Pacific District to Chicago's northern and western suburbs, which approach the terminal elevated above street level. It occupies the lower floors of the 500 West Madison Street building. The building occupies two square city blocks, bounded by Randolph Street and Madison Street to the north and south and by Canal Street and Clinton Street to the east and west. It is the second busiest rail station in Chicago, after nearby Union Station, the sixth-busiest railway station in North America, and the third-busiest station (after Grand Central Terminal and Jamaica station) that exclusively serves commuter traffic. History The 1911 station The Chicago and North Western Railway built the Chicago and North Western Terminal in 1911 to replace its Wells Street Station across the North Branch of the Chicago River. The new station, in the Renaissance Revival style, was designed by Frost and Granger, also the architects for the 1903 LaSalle Street Station. The Tyler & Hippach Mirror Company Factory was moved 168 feet east and 52 feet south to make room for the station's construction. At the time, this was the largest building ever moved. The station's 16 tracks were elevated above street level and "reached by six approach tracks and sheltered under an 894-foot-long [272 meter] Bush train shed." The upper level of the head house housed a concourse and other facilities for intercity passengers, including "dressing rooms, baths, nurses and matrons rooms, and a doctor's office." The centerpiece of the upper level was a stately waiting room, measuring 201 by 202 feet (34 by 62 meters), and rising 84 feet (approx. 26 meters) to its barrel vaulted ceiling. In addition to the main concourse on the upper level, there was a street-level concourse for commuters. During the heyday of rail travel, the Chicago and North Western Terminal was home to the C&NW's trains to Milwaukee, Minneapolis-St Paul, Madison and other cities of the upper Midwest, including the railroad's premier 400 series of trains. Until October 30, 1955, it was also the Chicago terminus of the trains the Union Pacific ran in conjunction with the C&NW, including the Overland Limited and the famed City trains (City of San Francisco, City of Los Angeles, Portland Rose)
