Quality of The Track Geometry Progress
Peňázová, Gabriela ; Volejník, Miloslav (referee) ; Svoboda, Richard (advisor)
The bachelor’s thesis deals with the development of track geometry over the course of time. The first part describes current system of measuring and evaluating of track geometry. The second part uses the described system on the specified track section of the double-track line Hodonín-Rohatec. The measured data provided by SŽDC are evaluated and compared with the track maintenance work. For the chosen sections the exponential and linear functions for the development of longitudinal elevation were established and we judge the possibility of using them for the prediction of track quality development.

Track Quality Evaluation
Joudal, Daniel ; Volejník, Miloslav (referee) ; Plášek, Otto (advisor)
This bachelor’s thesis is focused on comparison of two track geometry parameters quality evaluation methods. The compared methods are CZK, track quality index currently used in the Czech Republic, and TUG, track quality index developed at the Graz technical university in 2020. Data from the measuring carriages provided by Správa železnic (the Czech Republic’s infrastructure manager) were processed using the Matlab programme. There were three railway track section embraced in the thesis: Malšice – Sudoměřice, Sklené – Křižanov and Velim – Kolín. Track quality index graphs were made for all three railway stretches using both CZK and TUG methods, that were then compared.

The Relation between Track Geometry and Development of Long-Pitch Corrugation
Jung, Jiří ; Volejník, Miloslav (referee) ; Říha, Tomáš (advisor)
Thesis deals with the relation between track geometry and development of long-pitch corrugation in curves of small radii. In the frame of this diploma thesis, measurements of track geometry and measurements of long-pitch corrugation in the sections between Brno - Malomerice and Babice nad Svitavou were carried out. The measured data were processed and evaluated, while individual parameters were compared with each other and their dependencies were searched.

New Approaches to Section Evaluation of Track Quality
Joudal, Daniel ; Volejník, Miloslav (referee) ; Plášek, Otto (advisor)
This diploma thesis addresses track geometry parameters quality assessment. It specifically studies a new assessment method intended to be used by the track manager. The theoretical background consists of description of measuring means used on the railway network in the Czech Republic and other methods of track quality assessment used around the world. The practical part lists the advantages and disadvantages of the new method. There’s also a comparison of this new method with the method currently used method CZK and an analysis of the quality index evolution.

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.
