The Coal Transportation involved a literature search of all relevant documents written in 1970 or later. The purpose of this search was to identify factors which could serve as indicators of the energy/cost efficiency of coal transportation. The various modes of transportation considered were barge, mixed rail, pipeline, and unit train. Over 170 reports, articles, hearings, and other studies were gathered and reviewed. The majority of the documents dealt with coal transportation efficiency in a very general way disregarding specific route factors such as circuity, grade, return trip, etc. The information was evaluated and summarized in a computer file. A detailed review of the computer output identified a wide range of values for many of the mode, volume, and distance combinations. Examination of the bibliography revealed little first-hand information from coal transporters. It was concluded that: (1) The data base constituted by those reports written since 1970 and currently in the public domain does not contain sufficient specific data to allow meaningful comparisons of coal transportation modes. (2) BTU/Tnmi and cents/Tn-mi were the only factors specifically identified. Other specific route factors were generally not defined. Specific route factors which are essential to any inter-modal comparisons include: Circuity, grades, climatic effects, return of empties, unique terminal requirements, water availability, limitation of usage of transportation elements, and environmental impacts. (3) The impact of the specific route factors on the energy and cost requirements is significant. This precludes the use of the present data bank for any inter-modal comparisons of coal transportation.
