Which cities in the world have a metro or subway?

From Athens to Oslo – just one transfer by subway! How cool would that be?

This cool map (click for full version) shows all cities worldwide with or planning a metro system. It was published in 2007, so not all subway networks are displayed, and also our Facebook followers have already pointed out some flaws, but it sure is a cool idea to dream about and a nicely designed map!

Wikipedia’s metro lovers have created a nice list of cities with a subway / metro system, that should be more up-to-date. Here’s the current list of cities, including when they were built:
