During the last 30 years, major U.S. railroads adopted single-tracking as an economic measure resulting in tax savings, lowered maintenance costs, and reduced track investments. Single-tracing may have been only a quick answer to the railroads' problems. Only now are the long-term effects becoming apparent, particularly as railroads gain experience with the longer, heavier trains in use today. Problems of single-tracked lines include those of maintenance scheduling, the need to maximize maintenance of all system components, increasing rate of ballast degradation, increased frequency of track surfacing. Opinion within the industry in divided as to the economic validity of single-tracking as current problems are evaluated.
