SACRAMENTO, Calif. (AP) — California’s high-speed rail authority is breaking the promises made to voters when they approved $10 billion in bonds to build the nation’s first bullet train line, attorneys who represent Central Valley landowners argued Friday.

Proposition 1A, the ballot initiative voters approved in 2008, required the California High-Speed Rail Authority to identify funding for the entire first segment of the now-$68 billion rail plan and clear all environmental hurdles before starting construction.
