Interline Settlement System®

The Interline Settlement System® (ISS) is the centralized process for the rail industry used to negotiate and agree upon for the sharing of revenue generated for a movement when two or more roads are involved in the shipment route. ISS is the accepted industry standard method by which the rail industry settles interline freight revenues via Electronic Data Interchange (EDI).

Through EDI messaging, the system distributes revenue waybills, including rates and divisions, and provides a mechanism for concurrence prior to settlement, thereby eliminating most post-settlement disputes. ISS improves the efficiency, timing and overall quality of interline settlements. The ISS product, in conjunction with the Railroad Clearinghouse function, has resulted in savings across the rail industry for interline carriers. 

The rules for the ISS are included in the Railway Accounting Rules.
