Preliminary results of geodetic diagnostics of transition areas of ballastless track

Abstract

Construction of ballastless track is usually used in high-speed railway, which is suffered by high traffic load. The main reason is to reduce the maintenance costs of the railway line, although the initial costs of its construction are incomparably higher than with the classic construction. From the point of view of long term deformation analysis of railway track, the critical point of such the type of the construction seems to be the place of its completion and transition to the classical the railway superstructure. In terms of dynamic effects, it is a place with a change in stiffness and therefore a special attention is paid to its diagnostics.
