The railway is located in the historic Speicherstadt district of the city. In September 2015 the railway consisted of 15,400 metres (50,525 ft) of track in HO scale, divided into seven sections: Harz, the fictitious city of Knuffingen, the Alps and Austria, Hamburg, America, Scandinavia, Switzerland and a replica of the Hamburg Airport. Of the 6,400 square metres (68,889 sq ft) of floorspace, the model takes 1,300 m2 (13,993 sq ft).
By 2020, the exhibit is expected to have reached its final construction phase, including at least a total of ten new sections in a model area of over 2,300 m2 (24,757 sq ft). The next section is Italy and is scheduled to open in the spring of 2016. The exhibit includes 930 trains made up of over 14,450 carriages, 335,000 lights, 228,000 trees, and 215,000 human figurines. Planning is also in progress for the construction of sections for France, England, Africa and Australia.
