Evaluation of under sleeper pads influence in the test section in Planá nad Lužnicí railway station
Švanda, Tomáš ; Langer, Vojtěch (referee) ; Hruzíková, Miroslava (advisor)
Under sleeper pads (USP) are elastic layers positioned on the bottom surface of sleepers. Their aim is to slow down a deterioration of track geometrical parameters and reduce track maintenance costs. Three test sections with under sleeper pads have been built on the railway network in the Czech Republic. The effect of the under sleeper pads is continuously monitored. The height level of rails is measured by precise levelling. This thesis is focused on the Planá nad Lužnicí test section. It describes the precise levelling measurement in the 2015 and its evaluation and comparing with previous measurements. Furthermore track recording car measurements were evaluated.
