- LOS ANGELES (AP) - California voters are green-lighting the nation's most ambitious high-speed rail system, approving a nearly $10 billion bond to put speeding bullet trains capable of topping 200 mph between the state's major metropolitan areas. The measure, which passed with 52 percent support Tuesday, will fund the first phase of what is projected to be a $45 billion, 800-mile project built with state, federal, local and private money.
