Located in North Holland, Centraal Station is a major railway hub and the largest station in Amsterdam. More than 260,000 passengers use the station each day, making it the second-busiest in the country. As a national heritage site, Centraal Station also draws a number of tourists. It is visually beautiful, with a Gothic and Renaissance Revival style of architecture topped with an expansive cast iron roof. In 1997, renovations began that were scheduled to take two decades. The modifications will accommodate the new North-South Line to increase availability for commuters and tourists. It currently includes 15 tracks that provide passenger access for 21 trains. It also includes a Royal Pavilion where members of the royal family of the Netherlands can wait for transportation.
