The capacity of the nation's transport system to move increasingly large tonnages of coal from mines to markets is a major energy problem. Coal accounts for more ton-miles of freight on the railroads and the waterways than does any other commodity. This paper deals with belt conveyors , rail-barge combinations, and slurry pipelines as innovative additions to transport systems. In the past, both production and consumption have taken place within the same geographic regions. As late as 1969, the average lenght coal hauls was only 225 miles. With the opening of the western mines along with increased emphasis on having new power plants designed to use coal, the market is becoming national in scope. Average hauls are much greater, with some being as long as 1200 miles. Each of the modes is considered, including its level of energy efficieny, its advantages and constraints; and how it can including its level of energy efficiency, its advantages and constraints, and how it can contribute to the overall capacity to transport this vital source of energy.
