Legislators held another hearing at the state Capitol Tuesday on the project's recently released business plan.  The U.S. House of Representatives recently approved a spending bill that killed high speed rail funding for the current fiscal year.  But Dan Richard with the California High Speed Rail Authority says he's confident more federal funding will eventually come.

 "In the long term, if there's not a sufficient federal commitment, it won't be possible to build high speed rail as we envision it right now in California. But remember our business plan looks out about 25 years.  So this is really something we're talking about over the next generation."

California lawmakers say they're also worried about approving state bond funds for the project-at a time when California is cash-strapped. 

One Republican Assemblywoman-Diane Harkey-says she will make the case to pull the plug on the state funding.  Supporters of the project say it will create much-needed jobs in the state.
