This is the world's biggest train set which covers 1,150 square meters (12,380 square feet), features almost six miles of track and is still not complete.

Twin brothers Frederick and Gerrit Braun, 41, began work on the 'Miniatur Wunderland' in 2000.

The set covers six regions including America, Switzerland, Scandinavia, Germany
and the Austrian Alps.

The American section features giant models of the Rocky Mountains, Everglades, Grand Canyon ...

...and Mount Rushmore.

The Swiss section has a mini-Matterhorn.

The Scandinavian part has a 4ft long passenger ship floating in a 'fjord'.

It is expected to be finished in 2014, when the train set will cover more than 1,800 square meters (19, 376 sq ft) and feature almost 13 miles of track, by which time detailed models of parts of France, Italy and the UK will have been added.

It comprises 700 trains with more than 10,000 carriages and wagons.

The longest train is 46ft long.

The scenery includes 900 signals, 2,800 buildings, 4,000 cars - many with illuminated headlights...

...and 160,000 individually designed figures.

Thousands of kilograms of steel and wood was used to construct the scenery.

The 250,000 lights are rigged up to a system which mimics night and day by automatically turning them on and off.

The whole system is controlled from a massive high-tech nerve centre.

In total the set has taken 500,000 hours and more than 8 million dollars to put together, the vast majority of which has come from ticket sales.

Gerrit said: "Our idea was to build a world that men, woman, and children can be equally astonished and amazed in."

Frederik added: "Whether gambling in Las Vegas, hiking in the Alps or paddling in Norwegian fjords - in Wunderland everything is possible." It is the world's biggest model train set.
