Abstract
In a survey of track engineers and researchers, it was concluded that demands of increased tonnages may require some changes in track components but that today's track structure of welded rail on treated wood ties on crushed rock ballast will not change drastically in the next decade. The challenges of 100-ton cars, concrete cross ties, rail fasteners, and maintenance equipment are all discussed.
