Train crews carry a standardized piece of hardware to open restricted access doors, electrical cabinets, and control panels on passenger cars and locomotives. Instead of a traditional jagged profile, these tools often feature a square or triangular socket that fits over a matching lug on the latch. Having this tool prevents unauthorized passengers from accessing operating cabs or tampering with sensitive mechanical equipment.
