high-voltage Treatment for High Speed Rail

Feb 09, 2021The high-speed rail network, which was passed as AB 3034 in 2008 in the state legislature, initially set a 2028 San Francisco to Los Angeles opening date with a cost at $40 billion. By 2013 costs soared to $98 billion, but that price tag forced some serious cost-cutting back down to $68 billion. In 2018, the cost had creeped back up to $77 billion, with the start date pushed back to the
