===Timetable management===
The capacity the whole railway network is controlled by ProRail. Every year on the second Sunday of December the new timetable for the following year goes into effect. Planning this new timetable is done years in advance. In the planning stage all users can state the train services they wish to operate in this year. 

Companies using the ProRail network are:
* [[Nederlandse Spoorwegen]] (NS), using most of the network for long-distance [[Inter-city rail|intercity]]-services and local trains along the same lines. This network is commonly known as ''hoofdrailnet'' (main rail network).
* [[National Railway Company of Belgium|NMBS/SNCB]], [[Thalys]], [[Eurostar]] and [[Deutsche Bahn|DB]], which operate various international services to neighbouring countries (including local trains to those countries).
* [[Connexxion]] (including Breng), [[Qbuzz]], [[Arriva]] and [[Keolis Nederland|Keolis]] on the other contracted lines. Arriva is the biggest in this respect, with train running in the north, east and south of the country.
* Cargo operators including [[DB Cargo]], [[Rotterdam Rail Feeding]], [[CapTrain]], [[Rail Force One]] and [[Lineas]]. Most other cargo operators plan their trains shortly before departure, and thus are managed by Traffic Control.
* [[RailExperts]], [[Train Charter Services]] and many cargo operators use the network for charters, ad-hoc trains or empty movements. These are mostly planned at short notice, using empty pathing provided in the timetable.
