Design of the High Speed Track between Brno and Znojmo
Repko, Michal ; Velebil, Jiří (referee) ; Valehrach, Jan (advisor)
The aim of this diploma thesis is to design a new track route of high speed line from Brno to Znojmo, specifically between the planned terminal of high speed line Unkovice and existing railway station Hrušovany nad Jevišovkou. The track is designed for a maximum speed of 250 km/h. The alignment and profile of the line were designed, including the design of the railway superstructure and track geometry parameters.

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.

Evaluation of Tamping Method Trial Test Section
Tinka, Miloš ; Bombera, Ing Jan (referee) ; Svoboda, Richard (advisor)
The bachelor thesis deals with the evaluation of the influence of the modified tamping technology on the quality of the track geometry parameters. On the established test section, which is located on the doble-track line Břeclav - Přerov near the Rohatec village, a standard tamping technology was used on one track and the other modified. The adjustment consists in a larger number of tamping footprints, resulting in a larger reinforced surface of the sleeper bed beneath the sleeper. The aim of the thesis is to find out whether the modified technology will achieve a slower breakdown of the track geometry parameters and thus extend the time between the necessary repairs.

Optimalization of Mikulovice st. hr. - Hanušovice railway track, km 20,6 - km 23,3
Válek, Jiří ; Wrana, Radim (referee) ; Hruzíková, Miroslava (advisor)
The bachelor thesis deals with design of recontruction of the railway line Mikulovice st. hr. – Hanušovice in section from km 20,6 to km 23,3, that is located between stations Ostružná - Horní Lipová. The object of this thesis is improvement of the track geometry parameters, reconstruction of the railway superstructure and substructure, renewal of the drainage and elaboration of the bill of quantities.

Study of tram track lengthen to the town district Brno-Lesná
Pěknicová, Daniela ; Šamánková, Zdeňka (referee) ; Hruzíková, Miroslava (advisor)
This master’s degree thesis is aiming to provide design solution within extension of tram line no.5 in the town of Brno,which nowadays ends by balloon loop at Štefánikova čtvrť stop at Merhautova street in Černá Pole district. Proposed tram line is designed in the limits of local urban roads and ends by newly designed balloon loop at Okružní street in Lesná district. Within the framework of this thesis new tram super structure is designed together with surrounding urban rous and connection to Halasova náměstí.

Comparison of Plain Line Tamping Methods
Bombera, Jan ; Hartmann, Miroslav (referee) ; Svoboda, Richard (advisor)
The diploma´s thesis deals with evaluation of adjusted track tamping technology and its comparison with currently used technology. This is based on track geometry parameters measuring and its vertical movement on the test section, which was created on double track Břeclav – Přerov near Rohatec station. On this test section one line was tamped with the currently used method within regular maintenance work and the second line was tamped with the adjusted technology. The technology modification is based on application of increased number of tamping tines squeezing strokes, which results in a creation of bigger and more compacted sleeper bed. The point of this thesis is to verify, that the speed of the track geometry parameters degradation is smaller in case of adjusted technology use. Thanks to that it would be possible to extend the maintenance cycles in case of compliance with track parameters maintenance limits and traffic safety.
