Tram Transport - Public Transportation Backbone
Kopecký, Vojtěch ; Všetečka, Martin (referee) ; Valehrach, Jan (advisor)
The work Tram transport as the backbone of public transport deals with the issue of tram transport as the main mode of transport in the city of Brno. Emphasis is placed on the history of the Brno system, including its connection with trolleybus transport. Furthermore, the current state of the Brno street railway and fast trams and their supplementation by trolleybus transport are described in detail, including the processing of socio-economic data that determine the system. In comparison with other cities in the Czech Republic, but also abroad, its positive and negative aspects are identified. Based on this information, the potential future development of the system is processed, especially the construction of new lines and the improvement of existing tracks.

Tram Transport Serving as a City-forming Element
Csiba, Emese ; Plášek, Otto (referee) ; Valehrach, Jan (advisor)
The topic of this bachelor thesis is the description of existing solutions of individual structures in the field of tram transport. It is a catalogue of possible solutions for tram lines and stops and their basic comparison. The thesis includes analyses of existing designs of stops, alignments of different types of track, etc. and their assessment in terms of creating public spaces with tram transport.

Reconstruction of Railway Station Svitavy
Marek, Josef ; Rotschein, Petr (referee) ; Valehrach, Jan (advisor)
The goal of this thesis was to design the reconstruction of the railway station Svitavy. The line speed was rised from the current value to 160 km·h-1. New platforms were designed, therefore the railway substructure and the drainage were adjusted accordingly. Also, the effective length of the main tracks was extended to 740 m.

Development of Long-pitch Corrugation in Curves of Small Radii
Valehrach, Jan ; Kohout,, Martin (referee) ; Lidmila,, Martin (referee) ; Plášek, Otto (advisor)
Throughout the operation, the rails are worn and deteriorate. With the increasing speed of rolling stock, along with higher track loads and especially in the vicinity of major traffic hubs with a higher frequency of trains, defects that did not occur to such an extent before or were not considered to be significant, are brought to the forefront of the concerns of track infrastructure managers. Even though these defects are not directly restrictive to traffic operation, they are, in any case, a source of noise and vibration. One of these defects on the railway track is the micro-geometry defect of the running surface of the railhead. In directional curves with radii of less than 600 m or 700 m, defects known as long-pitch corrugation occur on the inner rail. In curves with 300 m or smaller radii, these waves are so distinct that they are a significant source of noise and vibration. In particular, vibrations affect the track surroundings and the track itself, as they cause other defects in the track structure. This dissertation deals with long-pitch corrugation, focusing on the monitoring of wave generation and development over time. The verification of the possibility to track the development of slip waves over time is the basis for possible future models predicting the development of defects. Numerous measurements of geometric parameters of the track and microgeometry of the railheads, specifically slip waves, have been carried out in the framework of the problem. Using RMS and peak-to-peak methods, the rate of development of defects over time and the relationship with other track parameters were evaluated. Based on the obtained development curves, intervals for further maintenance interventions were estimated. A part of the thesis focuses on the deficiency or excess of cant concerning the development of long-pitch corrugation.

Study of Tram Track Extension to the City District Brno-Medlánky
Seidlová, Vendula ; Janík, Jiří (referee) ; Valehrach, Jan (advisor)
The aim of the diploma thesis is to design the extension of tram line no. 12 from the current terminal station Technologicky park to the city district Brno-Medlanky. The tram track is situated on the separate road bed outside the built up urban area. Directional and elevational solution of the track is designed in several variants, after the evaluation the best variant is selected and elaborated. The diploma thesis contains the design of the tram stop and the terminal station with baloon loop, including access paths. Adjustment of the crossed road and the drainage system solution is part of the thesis as well.

Analysis of the causes and solutions proposed to tram transport delays from the transport and construction point of view
Kopecký, Vojtěch ; Svoboda, Richard (referee) ; Valehrach, Jan (advisor)
The thesis Analysis of the causes and solutions proposed to tram transport delays from the transport and construction point of view focuses on the issue of delays and speed drops in tram transport, especially on the causes of their occurrence and ways of their elimination. The thesis examines the current state of the Brno tram system, with a focus on the slowing elements in the system and the locations with frequent delays, including what causes these delays. The thesis also examines the possibilities of speeding up tram transport both from the point of view of transport and from the point of view of track layout. In the final part of the thesis, selected sections of the Brno tram system are analysed in more detail and on the basis of these analyses, measures are proposed that lead to the acceleration of tram transport and the elimination of delays that occur in it.

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.
