The Bay Rapid Transit System cost billions to build; a 2015 state audit said replacement value would be $21 billion. Then there is the $2 billion project to electrify the CalTrain commuter line between San Jose and San Francisco.
And when it is done, we all will benefit, not just commuters and businesses in the Bay Area. Like the L.A. subway and BART, an improved CalTrain will ease gridlock, enhance economic activity, and reduce air pollution and greenhouse gas emissions. The same will be true of high-speed rail.
