The China Railway Group and XpressWest Enterprises LLC are teaming up to build a high-speed railway to connect Los Angles to Las Vegas.

Initial plans included a 185-mile route that would run adjacent to Interstate 15 from Las Vegas to Victorville, approximately 85 miles northeast of downtown Los Angeles. The project is now being described as a 230-mile route with an additional stop in Palmdale and eventual service throughout the Los Angeles area using some of the same track that would be used by the publicly backed California high-speed rail project.

The agreement includes $100 million in initial capital, though there’s no information yet on how much the project will cost overall.

China’s first rail-related deal in the United States was a $567 million agreement inked in October 2014 to supply trains for Boston’s subway system.
