Brightline, the only privately owned and operated intercity passenger railroad in the United States, is owned by Florida East Coast Industries (FECI). FECI itself is a portfolio company managed by Fortress Investment Group, a massive global investment firm based in New York. In a broader ownership chain, Fortress Investment Group is primarily owned by Mubadala Investment Company, a sovereign wealth fund of the Government of Abu Dhabi. This makes Brightline a fascinating example of private, foreign-backed investment in American infrastructure. In 2026, the company continues to expand its footprint with the "Brightline West" project connecting Las Vegas to Southern California, maintaining its status as a high-speed rail pioneer that operates entirely independently of the federally-funded Amtrak system.
