This transaction set communicates an intermodal group loading plan, which outlines how cargo will be organized and loaded across multiple equipment units or vessel positions. Typically, a freight forwarder, logistics provider, or shipper sends the 715 to a terminal operator, rail carrier, or vessel operator who will execute the loading operations. The document is generally transmitted in response to a booking confirmation or loading request, detailing the specific arrangement of goods. Key segments include the BGN (Beginning Segment) which establishes the plan’s purpose and timeframe, the GR2 (Train Data) which specifies rail-related transportation details, and the GR4 (Loading Cluster) which groups equipment or positions that will be loaded as a coordinated unit.

Consider a scenario where Global Logistics Inc. has consolidated export cargo destined for multiple consignees and needs to organize it on a container ship and rail cars bound for Los Angeles. Global Logistics sends a 715 intermodal loading plan to Port Terminal Services, detailing how 47 containers should be distributed across four loading clusters—two clusters for the vessel’s forward holds, and two for rail transport to inland destinations. Within each cluster, individual equipment records (via N7 segments) specify container numbers, weights, and hazmat certifications, while R4 segments identify which terminal gates or vessel bay positions each container occupies. Port Terminal Services receives this plan and uses it to optimize dock labor, crane scheduling, and stowage operations.
