The analysis of dynamic effects in the frog region of railway turnout
Balash, Arsen ; Pazdera, Luboš (referee) ; Smutný, Jaroslav (advisor)
This thesis is focused on measurement and analysis of dynamic effects on railway turnouts. Two same-type turnouts with different fastening elasticity were chosen. My attention was focused mainly on the crossing part of the turnout, where the highest dynamic impacts occur. The point of the thesis is comparison of the crossing part of turnouts in term of dynamic behaviour and assessment of influence of soft rail pads on spread of dynamic energy through the construction. A part of the thesis is choice of methodology of the measurement and proposal of convenient mathematical apparatus for analysing of the dynamic effects on crossings.

Boskovice Connection Study
Jung, Jiří ; Sobotka, Lukáš (referee) ; Říha, Tomáš (advisor)
The thesis solves the design of the railroad called Boskovice connection, which is a line allowing direct connection for trains from Brno to Boskovice outside the railway station Skalice nad Svitavou. In the course of the work, the route of the connection is planned, including the connection to the Rajec-Jestrebi – Skalice nad Svitavou and Skalice nad Svitavou – Boskovice track section.

Two-way stereo speaker system
Kočvara, Pavel ; Polák, Ladislav (referee) ; Kratochvíl, Tomáš (advisor)
The Bachelor thesis deals with design of a passive two-way stereo speaker system with performance 50 W RMS / 8 for normal domestic use. With respect to its sensitivity 90 dB/W/m mid-range speakers Beyma 5MP50/N and tweeter Beyma T2030 were used. The enclosure is a type of bass-reflex and it is made of MDF material with internal damping from polyurethane coat.

Upgrading of Viskafors Railway Station
Blaňková, Monika ; Melecký, Martin (referee) ; Svoboda, Richard (advisor)
The main aim of the diploma thesis is reconstruction of Viskafors railway station and its adjacent track at KM146+ 800 - 145+ 700 so as to satisfy the current traffic and at the same time the legislation is met. The tracks geometry and turnouts in the station was solved according to Swedish and Czech standards and conventions. As part of the reconstruction, the connection of the service track was resolved from the north side.

Study of Žďárec u Skutče railway station reconstruction
Neuwirthová, Elisabeth ; Vacek, Josef (referee) ; Hruzíková, Miroslava (advisor)
The diploma thesis deals with the reconstruction of the railway station Žďárec u Skutče. The station is situated on the track Havlíčkův Brod – Pardubice-Rosice nad Labem. The aim of the reconstruction is to design the platform so that it meets the requirements of mobility-impaired persons. The work deals with track layout adjustments, the reconstruction of both the subgrade and the permanent way and the design of drainage. Also a bill of quantities and costs estimates were reckones.

Design of reconstruction of Krnov (Hanušovice) - Olomouc railway track, km 36,6 - km 39,6
Šíp, Radek ; Louma, Jaroslav (referee) ; Hruzíková, Miroslava (advisor)
The aim of the bachelor thesis is to propose a modification of the track geometry parameters and a complete reconstruction of the railway superstructure and substructure on the route Krnov (Hanušovice) - Olomouc on the section from km 36.6 to km 39.6 in the pursuit of minimalization of the displacement of the rail grid compared to the current situation. There is a loading station and the Nový Malín railway station in the track, where it is necessary to find a new location for the platform due to the reconstruction. This must meet the requirements for access for people with limited mobility, according to regulation No.398 / 2009 Sb. The reconstruction will also affect the handling track and the turnouts in loading station in Nový Malín. The result of this thesis is composing project documentations of horizontal and vertical solution, drainage and platform.

Analysis of dynamic effects acting on crossings
Vukušičová, Daniela ; Vukušič, Ivan (referee) ; Smutný, Jaroslav (advisor)
This thesis is focused on measurement and analysis of dynamic effects on railway turnouts. Two turnouts with different wear condition were chosen. My attention was focused mainly on the crossing part of the turnout, where the highest dynamic impacts occur. The point of the thesis is comparison of the crossing part of turnouts in term of dynamic behaviour and assessment of influence of the wearing depth on dynamic effects. A part of the thesis is proposal of methodology of the measurement and convenient mathematical apparatus for analysing of dynamic effects on crossings.
