The report documents results of a preliminary study to determine the technical-economic feasibility of hauling solid wastes by rail from urban areas to remote disposal sites. The rationale for a rail-haul system is discussed and various elements of the system, or factors influencing the practicality of rail-haul, are examined. These include: transfer stations and related refuse handling and compaction equipment; the position of railways in freight transport in the United States; suitability of various types of rolling stock for hauling refuse and other solid wastes; train configuration; and estimated costs. Consideration is given to implications of the rail-haul concept for operation of disposal sites, including use of strip-mine areas. Organizational, financial, and legal bases for transporting solid wastes by rail are outlined. The report includes numerous tables, diagrams, and maps.
