''Light rail'', et al., are nothing AND CAN BE NOTHING but money pits for the dumbass taxpayer, except in the 3 or 4 areas in the nation where gross population density is high enough to support them on a break-even or near-break-even basis.
Otherwise, they're pure USDA-inspected, Grade A, goobermint pork, for the benefit solely of the friends of the political class that pushed the boondoggle past the idiot voters.
I'd even take 50-70 percent farebox if necessary to cut congestion or avoid federal air quality sanctions. In this case 10% or less farebox?? Where is the sanity?? The pro-commuter rail bureaucrats in ABQ/SF took advantage of the Obama surge in NM to win approval of yet another tax to fund it.
