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.
