the oldest and largest high school United Nations simulation in the world. Den Haag Sculptuur is an open-air exhibition of sculptures; the tenth such event, in 2007, celebrated the 400 years of the relationship between the Netherlands and Australia. Since 2009, the city of The Hague also annually presents an LGBT-emancipation award called the John Blankenstein Award. The exact date of the ceremony varies each year. Notable people Transport Air The Hague shares an airport with Rotterdam. It can be reached from Central Station by RandstadRail Line E, with an Airport Shuttle to and from Meijersplein Station. However, with several direct trains per hour from the railway stations Hollands Spoor and Centraal, Amsterdam Airport Schiphol is more frequently used by people travelling to and from The Hague by air. Rail There are two main railway stations in The Hague: Hollands Spoor and Centraal Station, apart from each other. Because the two stations were built and run by two different railway companies in the 19th century, services have traditionally been split between the two: east–west lines terminate at Centraal Station, whereas north–south lines run through Hollands Spoor. However, Centraal Station now offers direct services to most major Dutch cities, such as Amsterdam, Rotterdam and Utrecht. Other destinations include Leiden, Haarlem, Zwolle, Groningen, Leeuwarden, Amersfoort, Enschede, Breda, Tilburg and Eindhoven. International travellers for Antwerp and Brussels have to change trains at Rotterdam. Urban transport Public transport in The Hague consists of a tramway network and a sizeable number of bus routes, operated by HTM Personenvervoer. Plans for a subway were shelved in the early 1970s. However, in 2004 a tunnel was built under the city centre with two underground tram stations (Spui and Grote Markt); it is shared by RandstadRail lines 3 and 4 and tram routes 2 and 6. RandstadRail connects The Hague to nearby cities, Zoetermeer, Rotterdam and Leidschendam-Voorburg. It consists of four light rail lines (3, 4 and 19 to Zoetermeer, Rijswijk, Delft and Leidschendam-Voorburg) and one subway line (E to Rotterdam). Road Major motorways connecting to The Hague include the A12, running to Utrecht and the German border. The A12 runs directly into the heart of the city in a cutting. Built in the 1970s, this section of motorway (the "Utrechtsebaan") is now heavily overburdened. Plans were made in the late 1990s for a second artery road into the city (the "Rotterdamsebaan", previously called the "Trekvliettracé") which is
