Railinfra
Prorail operates the Dutch railway network, which is one of the busiest railway networks in the world. The NS is currently the largest user of the Dutch railway network. Relined, a joint venture between TenneT and ProRail, was created to rent telecommunications infrastructure overcapacity to third parties. ProRail and Relined possess a dedicated fibre optic network (via high-voltage electricity pylons and alongside the railway tracks) that is used for their own telecommunications needs.
