The rail industry has received surprisingly little attention from private equity investors. There have only been 17 investments in the railroad industry by private equity investors over the last decade, according to the PitchBook Platform. The biggest investor in the industry has been Fortress Investment Group, which invested $4.1 billion between two companies, Florida East Coast Industries and RailAmerica. Another active investor in the industry has been The Riverside Company, which acquired Nordco in 2003 from One Equity Partners and added on three companies before selling it to OMERS Private Equity last month for an IRR of 31%.
