As a growing number of products and people are transported throughout the country via rail and on the nation's highways, the United States' infrastructure is in need of improvements to keep up with this rapid growth. During today's OnPoint, Ed Hamberger, chief executive of the Association of American Railroads, makes the case for freight rail as the best option for transporting goods in a clean and efficient manner. Hamberger responds to accusations that the rail industry has been charging customers unreasonably high rates and defends his organization's support of coal-to-liquids technology. Hamberger also explains what his industry needs from lawmakers in order to expand rail's capacity.
