Miniatur Wunderland - Largest model railway / railroad in the world

This is simply unbelievable. The "Miniature Wonderland" model railroad in Hamburg, Germany the largest in the world, covering 16,146 square feet of space with more than 10,000 train cars running around its 6.8 miles of HO scale track. Now, the makers of this huge layout have created a video that gives you a jaw-dropping look at the vast scope of this intricate work of art.

Its construction started in 2000, and is still underway, with a tiny airport due for completion by the end of this year. This is just the beginning — there are plans to double to layout by 2014. We especially like the Las Vegas portion, complete with dazzling LEDs lighting up the night.

You have to watch the new video to get the full impact of this remarkable achievement, which has taken in excess of 500,000 working hours to build. There's good reason why this is Germany 's most popular attraction, already visited by more than 5 million flabbergasted tourists.

I am impressed by the number of talents and ideas needed to get everything in place.
