New York Central originally used La Salle Street Station, sharing a route with the Rock Island Railroad as far south as Englewood. But after merging with the Pennsylvania Railroad to form Penn Central, all trains were consolidated onto the ex-Pennsylvania Railroad route, serving Union Station. Until 1965, Nickel Plate passenger trains used La Salle Street Station, connecting at JN.
