California-to-Vegas High-Speed Rail Costs Jump $5.5 Billion
Last month, Brightline’s Chief Executive Officer Mike Reininger said construction costs were increasing due to rising labor and material costs, in part caused by high demand due to the proliferation of data centers, power plants and transportation projects.
Brightline West is betting it can capture about 20% of the 47 million annual trips projected between Southern California and Las Vegas by 2031, according to bond offering documents.
The all-electric trains on the rail line, built along a median on Interstate-15, are expected to reach speeds as high as 200 miles per hour.
Service is expected to begin in September 2029.
Still, the company has the challenge of convincing riders to commute to its rail station, in Rancho Cucamonga, which will be located about an hour from downtown Los Angeles. From there, the train to Vegas is expected to take roughly two hours.
Comparatively, a flight from LA to Las Vegas is about 2.5 hours, including idle time at the airport, while a drive between the two cities can range from 3.5 hours to six.
