Miniatur Wunderland isn't your average model railway exhibit. We're talking 13,000 kilometers of track, almost a thousand trains, 335,000 lights, and more than 200,000 little figurines spread across a layout that's now takes up almost 14,000 square feet. Besides trains, there are also hundreds of little cars that drive around the various cities. It's Hamburg's most visited tourist attraction. Click on the More info-link.
