Yes, the State of California has promised to fund CHSR $1 billion/year until 2045, another $20 billion in total. Actually, only anther $15 billion because the present program lasts until 2030.
Good news, the IOS has been funded. Bad news, not enough funding in place to reach both LA and SF.
And there is always a possibility a future Governor would rather use this funding for something else, and redirects the funds. Future legislatures are not beholden to future expenditures promised today. They could kill this funding, or add more funding. It could go either way.
Never-the-less, California has still left CHSR in a condition of not being fully funded.
