The World’s Longest Indoor Model Railway Track

How big is your model railway? A few feet or larger? Everyone who builds model railways dreams of bigger and longer tracks. Some however just dream bigger.  

I’ve written about Miniature Wunderland before, the Hamburg model railway is the biggest model railway in the world and breaks all records. Perhaps my favorite record however is its track length.

Over the 6,400 sqm of floor space it occupies, its creators have crammed in an astonishing 15.715 meters of model railway track*! That’s 873 London Double Decker buses lined up, back-to-back!

Running around this are approx. 1,000 trains pulling over 10,000 wagons!

Watch it here:

I think I need a bigger shed! I have asked but unfortunately, Mrs MRE has put her foot down! 🙁
