A study of the quality and heterogeneity of ballast compaction in the transverse (along the sleeper) direction as a reason for the decrease in the stability of the track gauge geometry, and consideration of design and technological solutions for transition sections in order to increase the stability of the track gauge geometry and prevent an intensification of the growth in the number of track disorders. Purpose: transition sections. Methods: stamp testing of ballast layer material, statistical data analysis. Results: the results of measuring the deformation modulus of the sleeper base, studying the non-uniform elasticity, assessing the quality and homogeneity of the compaction of the sleeper base for various designs of railway tracks are presented, and design and technological solutions for transition sections are considered. Practical importance: the article presents design and technological solutions for transition sections aimed at reducing the period of stabilization of the ballast layer of transition sections; increasing the period of normal operation, taking into account the current dynamic loads arising due to the presence of joints, dynamic irregularities, non-uniform elasticity of the railway track, non-uniform compaction of the ballast prism of transition sections; ensuring the uniform elasticity of the ballast layer of transition sections.
