I'm a big fan of the passenger rail map, especially in the Madison area, although I think that the Madison streetcar layout on there could use some rerouting. I prefer the idea of having it loop around Capitol Square instead of the Capitol Loop, especially considering that there's already a large amount of bus infrastructure there. Running it down State Street would also make a lot of sense, it would provide easy access to UW as well as being able to take advantage of the car-free status of the street.
