Shipment Completed Date Date that all shipment legs are completed
Shipment Freight Forwarder Party responsible for coordinating car orders for a shipper and consignee.
Shipment Leg Shipments generally take several movements for Shippers to deliver full cars to Consignees. Each move will typically be performed by a distinct train. In advanced operations movements may be made by truck, air, or sea transportation mode.
Shipment Leg # Number of a train move. Leg zero is reserved for moving the requested number of empties from the current car locations to the shippers specified stop. Leg 99 is reserved for moving the empties from the Consignee’s specified stop to the Consignee’s service yard. Legs 1 to 98 specify the moves needed to move loaded cars from shipper to consignee. Generally leg 1 moves full cars from the shipper’s dock to its service yard. Leg 2 moves full cars from this service yard to the Consignee’s service yard, if that yard is the same as the Shipper’s service yard. Otherwise leg 2 moves the full car to the Consignee’s service yard via Way or Fast freight train as appropriate. If the Consignee service yard is many interchanges away, multiple shipment legs are required to move the goods.

If the railroad has no cars currently at the shipper’s industrial siding not in the home yard than the car or cars must be ordered from other yards in the same division or from foreign yards in other divisions. After the needed empty cars are assigned to a shipment, the shipment status changes to ‘In Process’. Empties are shipped to the shipper if needed and movement of empties from the consignee to the car home yard are provisioned. When all legs of an In Process shipment are completed, the shipment status is changed to Completed.
