President Joe Biden is heading to Las Vegas to showcase $8.2 billion in funding for 10 major passenger rail projects across the country, including to spur work on high-speed, electric train routes that could one day link Nevada and California, as well as Los Angeles and San Francisco.

The administration says the 218-mile (350.8-kilometer) train route linking Las Vegas and Rancho Cucamonga, California, about 40 miles (65 kilometers) east of downtown Los Angeles, may one day serve more than 11 million passengers annually.

The administration hopes the investment through federal and state partnership programs will help to boost prospects for the long-discussed project, which supporters say could revitalize travel in the American West and critics argue is too costly.
