But larger cities are probably going to have funding for more than buses. There aren't many cities that have any sort of mass transit rail systems, regardless of quality (which is somewhat subjective anyway), and to my knowledge those cities are all big-name cities: NYC, DC, Boston, maybe SF?, London, Paris...

And no, I don't count Buffalo's toy train as mass-transit rail s:) (OK, maybe on a technicality, but for most places, one line does not a mass-transit system make, any more than one bus route.)
