X12 715 — Intermodal Group Loading Plan
The 715 communicates an intermodal loading plan — which containers on which cars, in which order — between an intermodal terminal and a rail road.
Purpose
The 715 documents the loading plan of an intermodal train: assignment of each container or trailer to a specific car slot (double-stack, well car, spine car), loading order, equipment characteristics. It is generated by intermodal terminal operating systems (TOS).
It is the direct input for yard crane / reachstacker operations. Acknowledged by 997. Critical for capacity utilization of double-stack trains.
Envelope structure
The 715 travels within the three X12 envelope levels (ISA/IEA,
GS/GE with functional group IG, and ST/SE).

Common pitfalls
- Weight balance: a double-stack well car has a weight limit in bottom slot; a 715 placing a heavy box on top violates AAR Plate Standards.
- Domestic vs international: 53' domestic vs 40' international have different slot configs; mixing them causes mismatched loading.
- Hazmat consist rules: a 715 must respect buffer car distances for hazmat — same FRA rule as for 418.
