Abstract:Purpose: The paper poses some promising trends of modern projection science development for high-speed railway plan and profile. The main objective of the trends is to critically rethink the provisions of the existing regulatory design base of the projection. The question on inadmissibility of the arrangement of complex spatial geometry sections — the sections of coincidence of a vertical curve in a profile and a passage curve in a plan — is one of such provisions. Methods: In the frames of the conducted resea… Show more
