This is one of the things I wanted to see but didn't manage to do it in 2017 so we went there together. It's a giant maket of different parts of the country (mostly Sybiria and Ural, not so much of the cities) with train tracks, people, buildings and cute details like Putin riding a bear :D every once in a while the whole place goes dark and you see the places in the night! It was awesome.
