[July 2012] The metro in Madrid was modern compared with ones in London, Milan or Paris.
The trains themselves looked relatively new and there are no graffiti like Milan trains and felt brighter than the ones in London or Paris.
So, I looked up in the Internet and found that ' the length of the metro is one of the top 10, but the population in Madrid is only 25th in the world' and 'this metro was rapidly developed as Seoul and Bajing'.
Good thing that they developed it when the bubble was swelling.
