SACRAMENTO, Calif. (AP) — Gov. Jerry Brown scored a big win for California’s $68 billion high-speed rail project by persuading fellow Democrats to dedicate a steady future funding source for it in the state budget.

The $108 billion 2014-15 general fund budget approved Sunday includes $250 million this year from the state’s cap-and-trade greenhouse gas emissions fund. More important to rail supporters is the promise of 25 percent of all future cap-and-trade revenue each year, which could eventually total $3 billion to $5 billion a year.
