There are two model railroads in the world that lay claim as the largest model railway in the world: the Miniatur Wunderland in Hamburg, Germany, and the Northlandz in Flemington, New Jersey. However, Miniatur Wonderland contains approximately 39,370 feet of track compared to 50,000 feet for Northlandz, making Northlandz bigger.
The Guinness World Records also reportedly recognizes Northlandz as the biggest model railroad in the world. As part of the Northlandz exhibit, there are 100 trains, 3,000 buildings that compose cities and villages, and approximately 50,000 trees. It also contains approximately 400 bridges, some of which are 40 feet long. Bruce Williams Zaccagnino originally began Northlandz in his basement as a hobby before moving it to its current facility. The model railway is open to the public.
