Russian Subway stations: Went to one of the deepest metro stations of the world: Park Pobedy with a depth of 73m. Its escalator is 176m long and is amongst the longest in the world. It takes 2min and 57 seconds to do the whole trip. Furthermore there were a lot of beautiful stations, but navigating can sometimes be hard as you can see in one of the signs (at least for someone that cannot read cyrillic).
