LaSalle Street Station is a commuter rail terminal at 414 South LaSalle Street in downtown Chicago. It was a major intercity rail terminal for the New York Central Railroad until 1968, and for the Chicago, Rock Island and Pacific Railroad until 1978, but now serves only Metra's Rock Island District. The present structure became the fifth station on the site when its predecessor was demolished in 1981 and replaced by the new station and an office high-rise for the Chicago Stock Exchange. The Chicago Board of Trade Building, Willis Tower and Harold Washington Library are close by.HistoryThe first station on the site opened on May 22, 1852 with the completion of the Northern Indiana and Chicago Railroad. On October 1, 1852, the Chicago and Rock Island Railroad began using the station. The two railroads later became the Lake Shore and Michigan Southern Railway (New York Central Railroad) and Chicago, Rock Island and Pacific Railroad. North of a junction at Englewood Station, both companies' lines ran parallel to the terminal.
