ProRail (Dutch pronunciation: [proːˈreːl]) is a Dutch government organisation responsible for the maintenance and extension of the national railway network infrastructure (not the metro or tram), the allocation of rail capacity, and controlling rail traffic. Prorail is a part of NS Railinfratrust, the Dutch railway infrastructure owner. Its Utrecht headquarters is in the former offices of Nederlandse Spoorwegen (known as De Inktpot, "The Inkwell"), the largest brick building in the Netherlands. The building currently features a "UFO" on its facade resulting from an art program in 2000. It was established on 1 January 2003 when three separate organisations responsible for rail infrastructure in the Netherlands were merged. From Wikipedia
