Funding for a portion of California's high-speed rail was initially approved by voters in 2008. The project is now significantly delayed - and more expensive. The initial price tag was $33 billion. But according to estimates, it now could cost up to $128 billion to get it finished. A total of $87 billion of that would link Palmdale to Gilroy, south of San Jose. But as it stands, that portion wouldn't be ready until 2038.
