NMFC 165770: Carlines—Rail Car/Locomotive, Class 50

To find the correct freight class for your shipment:

1. List the commodity exactly on the BOL: “Carlines, single, railway car or locomotive — NMFC 165770, Class 50.” Include piece count and longest length.
2. Unitize wisely: band the single carline to a rigid skid, cap or pad sharp ends, and add edge guards. Mark handling notes like “Do not fork from ends.”
3. Quote at fixed Class 50; skip density calculators. Verify carrier overlength triggers (e.g., 96–120 in) and request overlength handling if needed.
4. Tag each piece with PO and job number for the railcar or locomotive work order to speed receiving in rail shops and maintenance facilities.

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

• Predictable Class 50 pricing streamlines LTL rate shopping and reduces reclass penalties.
• No density or packaging-based class shifts means faster tenders and fewer billing disputes.
• Accurate NMFC usage aligns with rail MRO workflows, improving dock throughput and parts traceability.
• Proper securement guidance lowers damage risk for heavy steel shapes, cutting claims and downtime.
