"High-speed rail was a signature Obama transportation policy during his first term, but many of the 13 projects that were signed up to receive funding have fallen by the wayside....However (and despite Elon Musk's claims about Hyperloop's superiority), the good stars lined up for the California High Speed Rail (CHSR)."

Even smaller jurisdictions like San Diego are revitalizing their trolley lines, creating an unprecedented rail renaissance in California."
