Railways Seals

What are railway seals and where are they used?

Railway seals are high-security barrier devices that lock the doors and hatches of rail wagons and rail cars, and they resist forced entry while giving clear evidence of tampering. Because different wagons need different locking points, the common forms are the railroad bolt — a long steel pin that fits varied latches — and the cable type, which threads a steel cable through a hopper or hatch mechanism. In addition, quality units are certified to ISO 17712:2013 “H” (High Security), so they suit high-value and cross-border rail freight. Once fitted, a bolt or cable can only be removed with cutters, and every unit is barcoded and serial-numbered for tracking.

Railway seals — frequently asked questions

Show FAQ

What seal is best for a rail wagon? A railroad bolt suits box-car doors, whereas a cable type suits hopper hatches and shifting loads. Therefore, the choice depends on the wagon and its locking point.

Are railway seals ISO 17712 certified? High-security bolt and cable types are certified to ISO 17712:2013 “H”, which suits high-value and cross-border rail freight. Always check the certificate for the specific product.

How are railway seals removed? A fitted bolt or cable can only be removed with bolt or cable cutters, so it delays intrusion. Because each unit is numbered, any interference is easy to trace.
