It's a whole bridge that was built once, but I don't know. There are trains going somewhere far away on it, hopefully for a beer.
On the downside, I want to note that the bridge will not teach you how to play dota at the Yatoro game level.
Trains travel very often, it's very exciting to look at them. The railway passes from several sides at once, one passes next to my house, but four stars because there is a hole under the bridge
