Last November, despite the down economy, California voters passed a bond of nearly 10 billion dollars to help finance high speed rail lines. By the year 2030, they'll link cities from San Diego to San Jose, Sacramento, and San Francisco. There are plenty of details that need to be worked out - from environmental impact reports to angry neighbors... not to mention financing the rest of the 60 billion dollar project. But high speed rail also provides a vision for California's transportation future. From San Francisco's new Transbay Terminal... to a stop at the yet-to-be-built Los Angeles international airport in Palmdale. By the time the rail is fully operational, the state is projected to be home to 50 million people... and that growing population will need lots of ways to get around. Quentin Kopp has been chairman of California's High Speed Rail Authority since 2006, but he's championed the project for decades. The retired superior court judge was a San Francisco supervisor and a state senator. KALW's Ben Trefny sat down with Kopp.
