Talks about a high-speed line between Amsterdam and the Belgian border started under Prime Minister Joop den Uyl (1973–1977); work began during Wim Kok's first term (1998–2002). The Rijkswaterstaat, a government agency under the authority of the Ministry of Transport and Water Management, was responsible for the organisation of the project. The Government of the Netherlands awarded the country's largest ever public-private partnership (PPP) contract to the consortium Infraspeed until 2030; it is responsible for design, construction, financing and maintenance. The line features state-of-the-art technology, including ETCS level 2 train control systems provided by Siemens AG and Alcatel (activities now part of Thales), and will be an ERTMS 2.3.0 Corridor.
