A CONTRIBUTION TO BALLAST MECHANICS

Most railroaders are apparently convinced that conventional track, will not meet the performance requirements of future traffic. It is clear that immediate progress will stem from current research experiments. In this paper the author described tests he conducted in conjunction with the Austrian Federal Railways to improve conventional railroad track. First, the effect of grain size, grain shape, and quality of ballast upon stability of the road bed were considered. This was followed by a discussion of the plastic and elastic settlement of the ties and a comparison between the behavior of the ballast bed and that of a spring model. Prof. Klugar introduced a new type tie called the "wing tie" devised to increase lateral stability. The author then discussed the lateral displacement of the track in connection with buckling tests in sharp curves.
