Russian metro train stations are also extremely gorgeous. They are all done differently with intricate designs, sometimes making passengers feel as if they are passing through a palace. There was no advertisements anywhere. But then when you look at all the communist symbols, slogans and architecture heavily embedded in design, you realize that the whole thing itself is a massive advertisement for the political system. Not surprisingly it was all sponsored by Stalin because he wanted to make them as people's place. Anyhow, those stations sets the example of how beautiful these transportation spaces could be. Any tourists to Moscow are definitely recommended to visit its best train stations (Eyewitness guide has a list).
