Figure 3-13. Tonnage on the Railroad Network: 2005
Although trucks carry most of the tonnage and value of freight, railroads carry vast quantities of goods over large distances. Bulk commodities such as coal and grain, moving in unit trains, dominate some rail routes, while intermodal trains carrying a wide variety of high-value products in containers dominate other routes.
Note: Figure shows railcar station-to-station annual shipment volumes (tonnages) as defined by Station Point Location Codes and by 4-digit Standard Transportation Commodity Codes.
