Holland has a railway network with intercity-, express- and local trains. All trains run regularly from approximately 6am until midnight. Most trains in Holland have a first and second class, except some local trains. Travellers do not have to make a reservation for a seat, unless they want to use the international trains from Holland to Belgium, France and Germany.
Holland train tickets: train tickets can be bought at counters at the large train stations in Holland or in vending machines that you will find on any train station. In some vending machines you only can pay with credit- or debit card. Other vending machines also accept coins, but not banknotes. In Holland there are train tickets with discount for children. It also is possible to buy an OV-chipkaart that travellers also can use for bus, tram and metro. An anonymous card costs €7,50, so probably only is worthwhile for a longer stay in Holland. There also is a disposable card. If you only make use of trains then it is advisable to buy paper tickets from the vending machines instead of buying an OV-chipkaart. This because paper tickets are cheaper than the OV-chipkaart if you use train services from multiple train companies.
Be aware that there usually are not enough seats in peak hours. This can certainly be uncomfortable when you travel with a lot of luggage. You do not need to pay to bring your luggage in trains in Holland. There only is a ticket of €6,- for bicycles and €3,- for pets. Keep in mind that it is not allowed to have your bicycle in the train between 06.30 and 9.00am and 04.30 and 6.00pm.
Holland train companies: most trains in Holland are from the NS, although there are some local trains that are from other companies like Arriva, Connexxion, Syntus and Veolia. If you use an OV-chipkaart and have to switch to trains from another company, then log out on the platform and log in again before you enter the next train.
Holland night train: in Holland there is a Night Net train in the Randstad. This night train runs every hour and stops at the large train stations Rotterdam Centraal, The Hague Hollands Spoor, Leiden Centraal, Amsterdam Airport Schiphol, Amsterdam Centraal and Utrecht.
International trains: there are high speed trains from Holland to Belgium, France and Germany, which can be booked with NS Hispeed. The Fyra train to Belgium is out of order due to technical problems, but there is an international train that temporary replaces the Fyra trains. Reservation for this train is compulsory if you go to Belgium, but not within Holland. Thalys to Paris also is available and reservation is compulsory.
