The Intermodal Control System (ICS) was designed by General Railway Signal Corporation (GRS, now Alstom, Inc.) for highway-rail at-grade crossings, under contract to the New York State Department of Transportation. In partnership with the Long Island Rail Road (LIRR), a site was selected for testing the ICS at the New Hyde Park station, where a grade crossing occurs close to the station. The planned project integrates train control, grade crossing control, and traffic control into a balanced system that can make decisions affecting both train speed and highway closure.
