Metro maps

I'm a big fan of the stylised maps often used by metro and railway companies, where geography is made secondary to conveying information, and as a result, the world is just a little bit more typographically pleasing. So obviously different levels of my geekery got together in rejoicing over this map:



Not a true metro or train map, although the buses go through plenty of tunnels, and the 300, 400, and 410 services even go under the sea for a bit. Another bit of the geek in me is happy that there seems to be some underlying systematicity in numbering the bus and ferry connections, although it could have been done a little bit more elegantly.
