Abstract

Nowadays in the field of railway lines designing and construction it is forbidden by normative base to combine transition curves in plane and vertical curves in profile. The purpose of the research is to prove groundlessness and inadmissibility of this prohibition by means of the analysis in the program complex “Universal Mechanism”. Consider more rational design a railways in using biclotoide curves, combine transition curves in plane and vertical curves in profile. It is necessary to consider abolition of the requirement about presence “clean” circular curve between transition curves by biclotoide curves. This analysis confirms the admissibility of such a combination. Accordingly, the combination of transition curves in plane and vertical curves in profile leads to reducing of interaction forces in the “wheel-rail” system, increasing of the motion smoothness, improving of the track stability.
