Since 1976, the growth in intermodal traffic in the United States has increased an average of 14 percent per year. This growth has placed an increasing strain upon the entire intermodal transportation system. In response to this growth, the railroads have attempted to increase the capacity of their terminal facilities. They have continued to expand the proportion of total freight capacity that includes trailer-on-flatcar (TOFC) equipment, and have begun to increase the use of TOFC unit trains in order to provide a high level of efficient service. The industry is responding to growth with a number of technological innovations, including computerized information systems; the development of lighter, more fuel-efficient flatcars; and new methods for more efficient loading and unloading of trailers onto and off of the flatcar units. The purpose of this study was to investigate the feasibility of constructing a private truck roadway on unused or abandoned railroad rights-of-way to serve this growing volume of trailer traffic and to do so in such a way that significant benefits, particularly drayage cost savings, could be obtained if such a project was implemented.
