The Transportation of U.S. Grains: A Modal Share Analysis 1978-2011 Update
contains new 2011 data and minor revisions to previous years. This supplemental report provides the most recently available annual data as an update to the full publication, published in 2011. The purpose of this analysis is to examine trends in the type of transportation used to move grains grown for the food and feed industry, identifying changes in market share among modes.
The data show the long-run trends in rail, barge, and truck transportation of grain continued into 2011 with minor decreases in rail and barge volumes and a small increase in truck volume. However, the total tonnage hauled by all modes decreased by 3 percent year to year as 2011 grain and oilseed production fell from 2010. Total tonnages were down for both export and domestic movements year to year with two exceptions: export movements by truck increased 158 percent to 19.8 milllion tons and domestic movements by rail increased 1 percent to 84.6 million tons.
