Thanks! That's certainly the look I was going for.

To answer your question, Austin has one line of light rail. It's essentially my Red Line on this map, although I added quite a few more stations. The termini in real life are Leander and Convention Center, with stations at Plaza Saltillo, MLK Jr. Blvd, Highland, Crestview, Kramer, Howard, and Lakeline. It's certainly light rail--it doesn't really go anywhere and it's mostly used by commuters who work downtown. There is talk of expansion, however as of now Capital Metro (the transit organization) only wants to use existing freight rail track, as they did for the Red Line. Possible routes, then, include an extension east to Manor (roughly following the eastern offshoot of my Green Line) and south to the Bergstrom Airport (roughly following the southern offshoot of my Blue Line). Unfortunately, it doesn't look like Austin will be getting any major urban rail network in the next few decades, at least. So I'm purely fantasizing about what would be great to have here.

I hope that gives you something of a picture of the situation here. Hope I haven't rambled on too long...
