Chicago's Grand Central Station

Grand Central Station Chicago

A little research and I was able to learn that the Pere Marquette passenger trains used Grand Central Station in Chicago for it's terminal not Chicago's Union Station.  I found the following on the net From Wikipedia:

"Grand Central Station was a passenger railroad terminal in downtown Chicago, Illinois, from 1890 to 1969. It was located at 201 W. Harrison Street in the south-western part of the Chicago Loop, the block bounded by Harrison Street, Wells Street, Polk Street and the Chicago River. Grand Central Station was designed by architect Solon Spencer Beman for the Wisconsin Central Railroad, and was completed by the Chicago and Northern Pacific Railroad.

Grand Central Station was eventually purchased by the Baltimore and Ohio Railroad, which used the station as the Chicago terminus for its passenger rail service, including its glamorous Capitol Limited 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 on November 8, 1969, and torn down in 1971."
