In addition to deciding the future of the country, voters in November will likely face a $9.9 billion bond measure for high-speed trains in California. The high-speed rail system that would cut through the East Bay, could zip commuters from Oakland to San Jose in 22 minutes. Rivaling short-haul airlines like Southwest with a two-and-a-half-hour rail trip to Los Angeles, the trains could ease traffic congestion and satisfy the state’s historic efforts to dramatically reduce greenhouse gases by 2020. Is this the right infrastructure investment? We give you the deal on the cost, technology, politics and possibilities.
