(2013) .1 These average energy intensity values represent the two-way transport average of upstream and downstream transport (upstream transport may require more energy to account for barge movement against downstream current velocities, and downstream transport energy may benefit from the river current)

reported that unit grain trains moving from Iowa to New Orleans, Louisiana, had route-specific fuel efficiency of 640 ton-miles per gallon, 54 percent better than energy intensity for an average train. Analysis of Selected Major Waterway Corridors The committee examined route comparisons across major waterway corridors with respect to metrics important to modal performance: (a)

The calculations for typical corridor-scale routes show that barge movements on the Ohio River and Lower Mississippi River use more energy than rail transport for the same origin– destination pairs, if system-average energy intensities are assumed, but that typical corridor-scale routes on the Upper and Lower Mississippi River and the Columbia River corridors may be more energy efficient than rail transport.
