The new estimated cost of building the Brightline West high-speed rail line from Las Vegas to Southern California, up from earlier projections of $12 billion. The private rail company, backed by Fortress Investment Group, has applied for a $6 billion federal loan as part of its financing plan. Brightline already secured a $3 billion federal grant in 2023 and has sold $2.5 billion in private activity bonds from Nevada and California to advance construction.
