Northlandz in Flemington, NJ offers a spectacular escape into the world’s largest model train museum. This exhaustive indoor world of extreme landscapes, contains over eight miles of track, hundreds of bridges (made of millions of tiny pieces of wood), more than 4,000 custom buildings and a half-million tiny trees placing it in the Guiness World Records as the Largest Model Railroad on Earth. Northlandz also is home to La Peep Dollhouse, a 94-room mansion complete with an indoor swimming pool, a ballroom with a doggie band and a two-story library. Then there's The Doll Museum, an exhibit of more than 200 collectible dolls from around the world. In The Music Hall, there's a 2,000-pipe organ at the centerpiece of a 400-seat theater. The organ is played on weekends and holidays. To round out the Northlandz experience, there's The Art Gallery, which has a cultural array of more than 250 paintings and other works of art. On top of all this, visitors can hop a ride on a 2/3-scale steam-train replica that travels through tunnels and over bridges, giving visitors a relaxing ride through the Northlandz woodlands.
