NMFC 166130: Railway Track Crossovers, Steel – Class 50

To find the correct freight class for your shipment:

1. List the item as “Crossovers, railway track, iron or steel – NMFC 166130, Class 50” on the BOL, and include piece count, longest length, and required loading method (forklift or crane).
2. Bundle long rails and crossover assemblies with steel banding on timber dunnage; cap sharp ends, use edge protectors, and mark Do Not Stack if geometry prevents stable stacking.
3. Match equipment to length: use LTL van service for segments under 12–14 ft; choose flatbed for longer or awkward assemblies and request tarps to limit corrosion on bare steel.
4. Balance bundles for safe handling, indicate center of gravity and lifting points, and keep skids wide enough for forklift tines to avoid damage and delays.

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

• Fixed Class 50 keeps dense steel trackwork economical, improving cost-per-pound for rail contractors and MOW suppliers.
• Simple, non-density rating speeds quoting and dispatch, reducing admin time across multi-stop rail construction projects.
• Accurate BOL details and proper bundling help avoid reclass, overlength, and handling accessorials that inflate freight spend.
• Correct classification aligns the right equipment the first time, protecting schedules for track outages and yard installations.
