Miniatur Wunderland (German for miniature wonderland) is a model railway attraction in Hamburg, Germany, and one of the largest of its kind in the world, built by the twins Gerrit and Frederik Braun. In January 2011 the railway consisted of 12,000 metres (39,370 ft) of track in HO scale, divided into seven sections: Harz, the fictitious city of Knuffingen, the Alps and Austria, Hamburg, America, Scandinavia, and Switzerland. Of the 6,400 square metres (68,889 sq ft) of floorspace, the model takes 1,150 m (12,378 sq ft).[1]
