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.

Assessment of Geometry Parameters of Track with Under Sleeper Pads
Škovranová, Michaela ; Volejník, Miloslav (referee) ; Hruzíková, Miroslava (advisor)
The diploma thesis applies to under sleeper pads. It researches thein using and benefits in foreign railvway authorities. Further it assesses track geometrical parameters in the trial track section with under sleeper pads in track Havlíčkův Brod - Okrouhlice and in the railway station Planá nad Lužnicí. There were evaluated measurements of vertical alingnment rails by precise leveling and deviations of track geometrical parameters measured by track meusuring car in the diploma thesis.There is expressed an conclusion about the impact of under sleeper pads on track geometric data in the thesis.
