Optimization of Skrochovice - Krnov Track Section
Loučka, Filip ; Wrana, Radim (referee) ; Plášek, Otto (advisor)
This thesis deals with design of optimization of the railway track situated between Krnov railway station and Skrochovice railway station. The section starts at km 87.892 at switch point of Krnov railway station and ends at km 90.4 behind the Krnov-Cvilín stop. The main goal of this work is to design geometric parameters of the track, reconstruction of the railway superstructure, restoration of the drainage and to propose a work technology. The work also includes working out of the bill of quantities and if it is possible a proposal of track speed increase. The design of railway crossings structure and the track on the bridge structure at km 90.367 was required.

Analysis of Possible Crash Avoidance of Personal and Rail vehicles at Railroad Crossings
Glogar, Matěj ; Bradáč, Albert (referee) ; Prnka, Jiří (advisor)
Presented diploma thesis deals with problems connected with accidents at railroad crossings from the road and railway drivers´ perspectives. The theoretical part is particularly focused on the explanation of chosen regulations associated with railroad crossings, with their construction and technical design and also with ways and options of marking in connection with railroad crossing safety system. The paper mentions the most frequent causes why dangerous situations occur. These causes arise from the railway and road drivers´ personal experience, supplemented by statistics of accidents at railroad crossings for the previous periods. The practical part analyses the options for averting a collision on two particular railroad crossings. For this purpose, the railroad crossing secured by lights and the railroad crossing secured only by a warning cross were chosen. Here, with Virtual Crash programme support, the origin of the chosen crisis situations is simulated and later options of their averting are evaluated. Finally, proposals for increasing railroad crossings safety are formulated for both cases. The appendix consists of a list of legislative regulations dealing with railroad crossings, a driving record of the rail vehicle and its technical parameters and simulation programme´s outputs.

Veseli Nad Moravou Station Reconstruction
Klar, Vít ; Sobotka, Lukáš (referee) ; Říha, Tomáš (advisor)
The subject of the Master's thesis is to design the redevelopment of the Veseli nad Moravou railway station. This renovation will include renewal of both, railway superstructure and substructure, including drainage system and new platform construcion proposal in order to meet current legislation regarding access of persons with reduced mibility and orientation skills. This thesis also deals with design of the track geometry compoments and geometry of set of switches at both heads of the railway station to fulfill the maximum train velocity demands at certain tracks. Last but not least, the rail track scheme of the station has been simplified.

Design of Optimization of Track Section Bylnice - Vlárský Průsmyk
Štěpán, Jan ; Mráz, Martin (referee) ; Plášek, Otto (advisor)
The focus of the thesis is to design a optimization of the geometrical layout of the track for an increase of the track speed to the highest possible value and a reconstruction of the permanent way superstructure between railway stations Bylnice - Vlárský Průsmyk. The work also includes a design of sleeper subsoil, renewal of the drainage and a design of the construction technology and procedures. Necessary view triangles will be added for unsecured level crossings.

Speed Increasing for Track Section Hradčovice - Luhačovice
Bětík, Václav ; Ing.Miroslav Hoza (referee) ; Svoboda, Richard (advisor)
The aim of this thesis is to prove possibility of track speed increase for the part of the track from Hradčovice to Újezdec u Luhačovic and the following part of the track from Újezdec u Luhačovic to Luhačovice. Speed increase is considered for current track parametres and for the track with proposed changes which shouldn´t significantly change the track profile. In areas where is a level crossing or a station head and so on, there is considered the speed limitation or these areas will be suggested as a subject of change.

Speed Increasing for Track Section Křenovice - Nezamyslice
Bombera, Jan ; Kroupa, Jan (referee) ; Svoboda, Richard (advisor)
Bachelor´s thesis deals with the possibility of increasing the line speed at Křenovice – Nezamyslice track number 315A. Speed increasing is tested in two steps – with current track geometry parameters and with changing some of the track geometry parameters, but always in order to meet regulatory and normative limit values. The new speed is determined for conventional vehicles and for vehicles that are able to take advantage of cant deficiency I > 100 mm. Speed limits in locations of railway crossings, signals position, etc., are taken into account for speed increasing. In some cases are proposed measures to change these objects.
