Rail freight company CSX is notifying about 40,000 current and former employees that their personal data was exposed.

The exposed data includes names, Social Security numbers, driver's license numbers and banking information. CSX also disclosed a separate April 2026 incident in which a third-party vendor may have disclosed data about current and former employees.
