Most routes have departures at least every half hour, busy stretches often as many as four to six departures an hour. There is a direct express train connection between the Amsterdam airport Schiphol and the most important cities in Holland and some cities in Belgium. Even at night, there is a train every hour between Utrecht, Amsterdam, Schiphol, The Hague and Rotterdam. The Nederlandse Spoorwegen, the Dutch railway company, operates an Intercity IC network connecting the big cities. These IC trains stop at the major stations.
Local trains provide transportation to smaller cities.
