HSL-Oost ( Dutch: Hogesnelheidslijn-Oost, English: High-Speed Line East) is the name of the now-cancelled high-speed railway line from Amsterdam to Germany via the Dutch cities of Utrecht and Arnhem. The scope of the project has now been reduced to some improvements to the existing railway between Utrecht and the German border. The railway between Amsterdam and Utrecht has been doubled from two to four tracks with the outer tracks prepared for 200 km/h and the overhead wiring prepared for the necessary 25 kV required for high-speed trains, though without 25 kV power supply, high-speed is not attainable. Still, it is expected that German ICE trains will be able to travel at 200 km/h from Amsterdam to Utrecht in the near future.
In 2009, a new feasibility study for HSL-Oost after the year 2020 was promised by Minister of Transport, Public Works and Water Management Camiel Eurlings.
