You can travel with 2 SNG couples from Amsterdam C. to The Hague C. Along the way you will stop at all stations in between. Until Nieuw Vennep the route is operated on the HSL-Amsterdam-Antwerp route, and the section Sassenheim - The Hague is operated on De Oude Lijn. Have fun!

The scenario should be playable without the non-bold files. Bypass the error message with F2. Without the bold files the scenario is unplayable.
U mag met 2 stellen SNG van Amsterdam C. naar Den Haag C. Onderweg stopt u op alle tussengelegen stations. Tot Nieuw Vennep wordt gereden op de HSL-Amsterdam-Antwerpen route, en het stuk Sassenheim - Den Haag wordt gereden op De Oude Lijn. Veel plezier!
