Mass transit subsidies are a colossal boondoggle. Atlanta, gridlocked by a 2inch snowfall, is trying to get big bucks for a trolley service.
The city's mass transit, MARTA, is a notorious money loser this is practically permanently dysfunctional. They once had a board chair that was a public housing resident, i.e. no job, no record of achievement.
No local gummit would spend money this way since taxpayers would see what a waste their money goes to but as a political system that makes some constituencies happy it works fairly well.
