A large gallery of subway maps that includes cities that you might not know have a subway system. The maps aren’t much to write home about, graphically speaking, and they don’t include light rail systems even when they’re a component of a metropolitan transit system (but to be fair, the same is true of buses, and you have to draw the line somewhere — and it is what it says it is: a collection of subway maps). But, as I said, the site’s strength is its completeness, which I find very impressive indeed. Via Mapperz.
