World's largest train set

Miniatur Wunderland in Hamburg is, according to the Guinness Book of Records, the world's largest model train set. It's so large—including airports, cityscapes and even seas—that to even call it a train set seems a good example of the German sense of humor. It covers 1,500 square meters, has 260,000 figurines in it , 9,250 cars, 1,040 trains, 42 planes, 385,000 LEDs, and cost 21 million Euros to construct.
