Multilevel Railcar Load Details

This transaction set communicates detailed information about the loading configuration and contents of multilevel railcars. Railcar operators, freight forwarders, or rail carriers typically send the 125 to logistics coordinators, shippers, or receiving facilities to document how a railcar is structured across multiple levels and to provide operational details. The transaction set is generally sent as a notification accompanying or following the physical movement of a loaded railcar. The BMM (Beginning Segment for Multilevel Railcar Load Details Transaction) segment establishes the overall context and references for the shipment, the N7 (Equipment Details) segment specifies railcar characteristics and configurations, and the G62 (Date/Time) segment records critical timing information such as loading dates or scheduled delivery windows.

For example, Midwest Rail Services loads automobiles destined for a dealership network and sends an X12 125 to Logistics Plus, the third-party coordinator managing the shipment. The transmission includes details in the N7 segment identifying the specific railcar number, capacity, and how the automobile inventory is distributed across the railcar’s multiple levels. The G62 segment timestamps when the loading was completed, and any motor vehicle control details in the VC (Motor Vehicle Control) segments document individual vehicle identifiers and positions within the load. Logistics Plus uses this transaction set to verify load composition before the railcar departs and to prepare receiving instructions at the destination facility.
