Is there a government sponsored transportation system that does not bleed money? That's a real question (not a sarcastic "I already know the answer", statement).
I know that the Public Transportation System in Austin was millions of dollars in the red every year, and it's the same thing in Memphis. The "DART" program in Dallas has never been in the black, and the rail system in San Fran was so costly and the ridership was so low that it would have been more cost effective for the city to lease a Chevy Tahoe and pay the gas for every individual rider. AmTrack? Has anyone been on one of those trains?
I don't believe any of the subway/metro systems in the US make money, but they are critical to the larger transportation needs of several US cities, more than making up for their cost in greatly lessening traffic and the necessary infrastructure to support it. New York City and DC are the two best examples of this in the US, both cities basically can't function effectively without their mass transit sytems.
