Brightline West, the proposed high-speed rail line between Las Vegas and Southern California, has until Nov. 2 to make a $400 million equity investment in the project, according to The Bond Buyer.

It hopes to receive a $6 billion Railroad Rehabilitation and Improvement Financing loan by late October, according to The Bond Buyer.

The loan may be the “key to the project's future” in the eyes of investors, The Bond Buyer reported.

Yet, that’s where the California High-Speed Rail Authority is placing its bet to fund future construction.

It entered a co-development agreement in June with a consortium of high-speed rail, infrastructure and investment firms in hopes of attracting outside investors.
