RAS will be designated to receive supporting electronic data from the Railinc Car Repair Billing Exchange (CRBX) System. In order to maintain an accurate and complete repair history, bills from railroads that do not subscribe to the CRBX service will be keypunched by RAS at the detail level and added to the Railinc file. At the close of the designated accounting period, a reconciliation of the actual bills versus the electronic data will be performed. Discrepancies that cannot be corrected or adjusted will be documented as part of that period’s reconciliation report. RAS will maintain a detailed historical database of repair records for the life of each railcar and will use this data to produce maintenance reports designed to meet individual customer’s requirements.
