The aim of this work is to study track speed increase in section between Boří les – Hrušovany nad Jevišovkou – line Břeclav – Znojmo. In terms of this work directional and height adjustment is beig suggested. The ambition was to ensure basic accessibility of this area within existing range. The study was prepared and respects costs.

Diploma thesis studies a possibility of doubling track between Chlumec nad Cidlinou and Hradec Králové. It proposes some solutions which differ in the lenght of the track section where track speed is increased to 160 kmph. Also, the possibilities of elimination of railway crossings with the roads of any category are examined and overview of costs for construction.

In this paper, a statistical method is developed to improve predictive maintenance on railway track. The problem tackled is being able to predict when the next maintenance event should take place to guarantee a certain track quality class. To solve the problem, The prediction is made using track measurement data exclusively, with no maintenance history to support the data analysis. The dataset consists of track measurements taken over eleven years and 170 kilometres on the Bothnia line in Northern Sweden. Different track degradation models and machine learning approaches are discussed and implemented. In the end, the tool developed was able to predict track degradation with an error within reasonable bounds of the typical maintenance limit. This will allow an operator to predict the recommended date for the next maintenance event at all locations using only historical track measurements as an input and little to no user intervention on the programme. / I denna uppsats utvecklas en statistisk metod för att förbättra förebyggande underhåll av järnvägsspår. Det problem som utreds är att kunna förutsäga när nästa underhållsarbete bör äga rum för att garantera en viss kvalitetsklass på spåret. För att lösa problemet användes endast spårmätningar utan någon underhållshistorik som stöd för dataanalysen. Data består av spårmätningar som utförts under elva år och 170 kilometer på Botniabanan i norra Sverige. Olika modeller för spårförsämring och metoder för maskininlärning diskuteras och implementeras. I slutändan så kunde det utvecklade verktyget förutsäga spårets nedbrytning med ett fel som låg inom rimliga gränser av den typiska underhållsgränsen. Sammanfattningsvis så kommer detta att göra det möjligt för en operatör att förutsäga det rekommenderade datumet för nästa underhållsarbete på alla platser med endast historiska spårmätningar som indata och med liten eller ingen användarintervention i programmet.

The aim of the diploma thesis is to design of reconstruction of the Ždírec nad Doubravou railway station and Hlinsko v Čechách railway station, and to allow access for persons with reduced mobility. Resolving a modification of the track (reconstruction gridiron), design the reconstruction of the substructure and drainage railway stations.

The aim of the thesis is a reconstruction of Nedvědice railway station. The thesis contains modification of track geometry parameters of the railway, reconstruction of the railway superstructure and railway substructure. Platform with the platform edge height of 550 millimetres above the top of rail was designed. Design of a railway crossings according to valid regulations is other part of thesis. The thesis also include drainage system renovation.

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.

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.

The diploma thesis focused on study of the reconstruction of the railway station Rájec-Jestřebí. During the reconstruction it is necessary to solve the increase of speed in the main tracks to 160 km/h, full peronization of the station and modification of the railway substructure with drainage.

The aim of this master’s thesis is the design of railway junction from high-speed rail RS1 Bohumín – Přerov to railway station Hranice na Moravě at a speed 160 of kph. The design has been developed with minimisation of land occupation and the minimisation of engineering structures. The next aim is the design of two pairs of railroad switch on the high-speed rail. Part of the thesis is the design of the railway substructure, railway superstructure and track drainage.

The master‘s thesis deals with a line of a new tram track, which will merge the current tracks in the street Kounicova and in the street Štefánikova. The track continues through the area of Jasels barracks, through the street Dělostřelecká, where its ended by a tram loop. A part of the thesis was also a design of the new stop layout.
