What is the Waybill Data Base?
Answer. The Carload Waybill Sample (Waybill Sample) is a stratified sample of carload waybills for terminated shipments by rail carriers. These railroads may file waybill sample information by using either: (1) authenticated copies of a sample of audited revenue waybills (the manual system); or (2) a computer generated sample containing specified information (the computerized system or MRI). The waybill submissions from these two methods are combined in a 900 byte Master Record File. From this master file a Public Use Waybill File is created.
