Some people build big model train sets, but there is nothing on the size of Miniatur Wunderland.

Located in Hamburg, Germany, the Largest model train set has a huge total length of 15,400 m (50,525 ft). To put that into perspective, the length of the train set is enough to get you to the top of Mount Everest - and 6,000 m back down the other side!

The trains make up part of an enormous miniature world which spans eight countries (well, not literally).

Miniatur Wunderland has a floor space of 1,499m², and includes miniature versions of Germany, the US, Denmark, Norway, Sweden, parts of Finland, Switzerland and Italy.

Construction is underway on a new Venice section, with the addition of Monaco and France also expected at some point.

Consisting of 2,633 figurines, 4,340 buildings, 130,000 trees, rivers, mountains, cityscapes and more, Miniatur Wunderland truly is a reflection of many different landscapes across the globe.

The attraction has roads, with 11,000 moving cars, its own airport, with 60 planes that take off and land, and of course trains for their tracks - 1,300 of them!

It took five years to fine tune the programming for the cars and aeroplanes, ensuring they ran smoothly and largely autonomously.

Miniatur Wunderland has its own dedicated control centre, with 50 computers that track and control the planning.

Three of the computers are used for the airport alone due to its complex programming.

The attraction has a total construction cost of €21 million, excluding the latest additions, and has held the record since September 2015.

Our team spoke to Gerrit Braun, co-founder of Miniatur Wunderland, about his inspiration for the project.

"As children we played a lot with model train sets. Somehow this hobby just disappeared one day, but we still kept the passion. And then one day, we decided to create a miniature Germany and the Largest model train set."

To celebrate receiving their Guinness World Records title, Miniatur Wunderland created their very own adjudicator figurine, which now stands outside the miniature version of the building facade.
