Interesting Metro site

Somebody, clearly somebody fascinated with transportation systems, has a bunch of pages devoted to DC's Metrorail, with pictures of all the stations in the system, movies taken in many of them, and information about the unique features & architecture of each station, as well as stuff about the different kinds of trains the system has running. My reaction alternates between "Somebody had too much time on their hands" and "Wow, this is pretty neat!"

In the fall, I always kinda wish I had a camera to take pictures of the trees from the Silver Spring station. There's no pic of that here, alas, but there is a photo of the other fun thing at Silver Spring: Penguin Rush Hour! [Edit: Metro's own website has three photos of the mural, starting with this page.]

The main site also covers rail systems in NYC and Pittsburgh, as well as bus systems in DC and some VA cities.
