There are now two categories of international trains. The different categories are described below:
The international services between Amsterdam and Paris (France), and between Amsterdam and Frankfurt (Germany) are operated by dedicated high-speed trainsets. These services run approx. every two hours from early morning up to the beginning of the evening.
Regular Day Services
The hourly service between Amsterdam and Brussel (Brussels, Belgium) is operated by NSH coaches and a Belgian locomotive in push-pull mode. Some services have been taken over by TRAXX locomotives class E186, that will take over all services once they are allowed to operate over the new high-speed line. The 2-hourly service from Amsterdam to Berlin (Germany) consists of German InterCity coaches, on the Dutch part hauled by an NS-Reizigers electric locomotive.
