Shipment Routing and Car Assignment

Purpose | Screen Images | Data Description | Function Descriptions | How to Use


The next hour after the seller's shipment 'paperwork' arrives at the railroad back office, each car needed for the shipment is assigned to the shipment. A route is then created from getting the empties needed by the shipper, if any, to the shipper to picking up the cars and bringing them back to the yard serving the seller and so forth until the consignees has emptied the loads and they are returned where they belong. Many trains may be involved with any shipper/consignee transaction. Empty management can involve multiple moves initially and when the consignee is done with the cars.

Screen Images:

The next figure is a sample of the route legs associated with shipment number 900000068. legs 1 up to 98 define the sequence to route legs for the full car(s) in the Shipment from the Shipper's dock to the Consignee's dock. For each car and each route leg, a waybill is created. The start and destination for each route leg must be reachable on a single train (or intermodal move).

Leg 0 is created by MRRM to move the Empty car(s) to the Shipper's loading dock either from the Yard serving the Shipper or from other trackage owned by the Shipper.

Leg 99 is created by MRRM to move the Empty car(s) from the Consignees stop to the Yard serving the Consignee.
