LaSalle Street Station is a commuter rail terminal located at 414 S. LaSalle Street in downtown Chicago, Illinois, serving Metra's Rock Island District. It served as a major intercity rail terminal for the New York Central Railroad until 1968 and the Chicago, Rock Island and Pacific Railroad until 1978. The present structure is the third station to have existed on the site. The previous structure was demolished in 1981 and was replaced by the current station and a new office high-rise for the Chicago Stock Exchange. The Chicago Board of Trade Building, Sears Tower and Harold Washington Library are close by.
