1 "All Modes" include shipments by other modes not separately listed on this table, such as pipeline and multimodal shipments such as parcel, postal and courier; truck and rail; truck and water; rail and water; other multiple combinations, and unknown modes. Hence the sum of the four modes shown here will not equal the total.
