Szukana fraza: [Abstrakt = "The paper presents the issue of durability of railway tracks in view of infrastructure investments. The sustainability of the railway network should be taken into account during the risk assessment of infrastructure projects. The paper presents an analysis of railway investment risks along with the possibility of reducing it by increasing the durability of the railway tracks using an example of turnouts with Under Sleeper Pads. The results of the measurements of turnouts with Under Speepers Pads \(USP\) and without USP are presented. The measurements included an analysis of the vertical profile of the turnouts and the prop\-agation of vibration as a result of applying the USP in comparison to the case without the USP. The results of the research have shown the relevance of conducting the research into the USP impact on the durability of turnouts."]
