Moving large volumes of freight over long distances is an energy intensive proposal and something we do very regularly these days. In fact, with the rise of globalization humanity is now moving more over greater distances than ever before. Moving cargo by rail is the second most efficient means of transporting it—the first being transport over water. Coal is the commodity whose movement on railroads accounts for the largest percentage of tonnage moved by Class I Railroad operators in the United States (44%) and the largest percentage of gross revenue, when divided out by commodity type, for these operators (24%).

Today’s market size is the tonnage carried by U.S. Class I Railroads in 2010 and the value of the corresponding gross revenue earned for their transportation. The revenue number does not adjust for such things as incentive rebates offered by the railroad operators. U.S. Class I Railroads in 2010 were the following: BNSF Railway, CSX Transportation, Grand Trunk Corporation, Kansas City Southern Railway, Norfolk Southern Combined Railroad Subsidiaries, Soo Line Corporation, and Union Pacific Railroad.
