NMFC 166390 - Railway Track Derailers | Class 50

To find the correct freight class for your shipment:

1. List the commodity as “Railway Track Derailers, iron or steel” on the BOL to lock in the fixed Class 50 and avoid density disputes.
2. Palletize or crate heavy derailer bodies; band tightly with steel or heavy-duty poly strapping, and block/bracket to prevent roll or slide on deck.
3. Protect flag/target assemblies by removing and boxing them, or shield protrusions with edge guards and foam so cross-docks don’t bend indicators.
4. Load with a forklift using solid lift points; keep all pieces within pallet footprint (no overhang) and mark center of gravity for safe handling.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Predictable Class 50 rating simplifies quoting and reduces reclass risk, stabilizing LTL costs for rail maintenance suppliers.
• Non-hazardous status avoids hazmat fees and speeds tendering, improving dock-to-dock cycle times for urgent track work.
• Dense steel hardware travels efficiently, enabling better cube utilization and lower cost per pound on multi-stop utility runs.
• Clear NMFC alignment helps minimize inspection holds and OS&D claims, lowering administrative overhead and chargebacks.
