Grand Central Station was a passenger railroad terminal in downtown Chicago, Illinois, from 1890 to 1969. It was located at 201 West Harrison Street on a block bounded by Harrison, Wells and Polk Streets and the Chicago River in the southwestern portion of the Chicago Loop. Grand Central Station was designed by architect Solon Spencer Beman for the Wisconsin Central Railroad (WC), and was completed by the Chicago and Northern Pacific Railroad.The Baltimore and Ohio Railroad purchased the station in 1910 and used it as the Chicago terminus for its passenger rail service, including its Capitol Limited service to Washington, D.C. Major tenant railroads included the Soo Line Railroad, successor to the Wisconsin Central, the Chicago Great Western Railway, and the Pere Marquette Railway. The station opened December 8, 1890, closed November 8, 1969, and was demolished in 1971.ConstructionIn October 1889, a subsidiary of the Wisconsin Central Railroad began constructing a new passenger terminal at the southwest corner of Harrison and Wells Streets in Chicago, to replace a nearby temporary facility. The location of this new depot, along the south branch of the Chicago River, was selected to take advantage of the bustling passenger and freight market traveling on nearby Lake Michigan.
