From the Daily Mail:
Northlandz model railroad, in Flemington, New Jersey, was painstakingly constructed by hand and took 16 years to complete.
Bruce Williams Zaccagnino started the project as a hobby in his basement with the help of his wife Jean before opening its doors to the public as a tourist attraction in 1997.
The model railway has an impressive 100 trains, 400 bridges and more than nine miles of track, as well as 3,000 miniature buildings that make up idyllic miniature towns and villages.
There are also 50,000 streets and 40ft bridges spanning across vast canyons, all of which Mr Zaccagnino designed and painstakingly handcrafted on his own.More photos and information at the link.
