To improve the transport service of every country at the required level, it is necessary to set up appropriate infrastructure, including railways, and the necessary facilities of satisfactory quality. After the establishment of the Slovak Railways (ŽSR), the condition of the railway infrastructure was judged to be unsatisfactory. This situation urgently required optimisation of track sections, which are included in the trans-European corridors. The basic aim of optimisation of the railway network of ŽSR is to build a highquality, safe and reliable railway, which, due to its excellent quality, will correspond to the standards of advanced European countries and, at the same time, provide interoperability. Due to this, it was necessary to verify the fulfilment of the prescribed quality parameters on the optimised lines, among others, and also bear the capacity of individual structural parts of the sub-ballast layers. To address this aim, this paper deals with optimised corridor no. Va in the Považská Teplá - Žilina section, where the diagnostics of the quality of the sub-ballast layers was conducted. This paper specifically focuses on the evaluation of the determined values of the bearing capacity of the construction layers of the embankments and their foundations as well as the transition areas between the objects of sub-ballast layers and embankments located in the optimised section of the line.
