The miniature wonderland in Hamburg is an attraction of the superlative. In the biggest HO-scale model train installation in the world, on a surface of over 6000 square metres, there are around 830 trains with 15,000 wagons controlled by 36 computers. A further 200,000 moving miniatures and about 300,000 lights complete the wonderland. Walking through this attraction takes one through many parts of Germany, Austria, Switzerland and Scandinavia. In 2008 it was visited by over 1,000,000 people.
