摘要：
Two planning studies were performed which identified track system rehabilitation and maintenance problems, suggested candidate subprograms for solving the problems, and evaluated the subprograms. The two sets of evaluation results were combined to yield a single list of subprograms rank-ordered according to a multi-criterion measure of desirability. This report summarizes the two studies, it describes in summary fashion how two sets of evaluation results were combined, and it presents the combined rank-ordered list of recommended candidate subprograms.
