PLANES take off, passengers wander through terminals and workers tend to the jets, but this is no ordinary airport.

The world’s largest model airport/railway, the Knuffingen Airport, has gone on display in Germany.

The incredible model is based on Hamburg Airport and features 40 planes and 90 vehicles that autonomously move around the airport.

It took seven years to build and cost a staggering $4.8 million.

The model includes a “carsystem” that manoeuvres the vehicles by computer. Meanwhile tiny wires move the planes, making them appear to fly.

Passengers appear to walk around the terminals and the vehicles even feature flashing lights and indicators. A series of lights around the miniature airport give it a bluish glow.

Luggage, carts, staircases and carparks are also featured in the 150 square-metre display, which also showcases a variety of planes from Airbus A380s to Cessnas.

There are approximately 40,000 lights, 15,000 figurines, 500 cars, 10,000 trees, 50 trains, 1000 wagons, 100 signals, 200 switches and 300 buildings.

It is on display at Miniatur Wunderland in Hamburg, Germany.

The real Hamburg airport opened in 1911 and now covers almost six square kilometres.
