The Richard B. Ogilvie Transportation Center is a passenger terminal in downtown Chicago, Illinois. It occupies the lower floors of the 500 West Madison Street building. The Chicago and North Western Railway built the Chicago and North Western Terminal in 1911. The new station, in the Renaissance Revival style, was designed by Frost and Granger. In 1984, the head house was razed and replaced with the glass-and-steel 42-story Citicorp Center (now 500 West Madison), which was completed three years later in 1987. However, much of North Western Station's rail structure was below street level, so Metra service was maintained with only minor interruptions during construction. The station was renamed the Ogilvie Transportation Center in 1997. (wikipedia.org)
