LAS VEGAS • A planned high-speed rail line between Las Vegas and the Los Angeles area got a Biden administration pledge on Tuesday of $3 billion to help start laying track, Nevada elected officials said.

The $12 billion project led by Brightline West has been talked about for decades, and U.S. Sen. Jacky Rosen told reporters that it now has all required right-of-way and environmental approvals, along with labor agreements, for work to start on some 218 miles along the Interstate 15 corridor.

No date was announced for work to start. But Rosen said electric-powered trains could be carrying passengers by the time Los Angeles hosts the Summer Olympics in 2028.
