"After the final environmental documents are approved, construction could start in 2026. Brightline West already has approvals for construction of a 170-mile portion of the line from Victor Valley, California, into Las Vegas, where a terminus is planned about two miles south of the Strip in Downtown Las Vegas. Operations could begin as soon as 2030. Full funding for the project has not been identified, with Brightline planning to seek both federal and private dollars once the environmental documents are approved."

2030? that's a long way off. Victor Valley to Las Vegas - Downtown in 2 hours 20 minutes.
