"Currently, proponents are working on a 10-year, $25 billion plan to link population centers in San Jose, San Francisco, Los Angeles, San Diego and Sacramento with a 220 mph train, redirecting millions of travelers away from clogged freeways and airports. The trains could be up and running within a decade--if our elected officials ever get on board. The barrier to high-speed rail in the United States isn't, as some might assume, technology--it's politics. State of the art rail systems are there for the taking, but elected leaders generally won't support anything on rails."
