The topic of the diploma thesis is the design of a new Brno main railway station in the position "The River" (Ac), which was selected from several variants of the reconstruction of the Brno railway junction (ŽUB). The aim of this work is to create an architectural and urban concept, the function of which will be an important contribution to the development of the city of Brno, improving the traffic situation and comfort of the general public or residents of the new adjacent district Trnitá. The solved area is located in the cadastral area of Komárov, Štýřice and Trnitá. The height dominant is represented here by the Europoint building (115 meters). It is located in the axis of the new boulevard, at the other end of which we can see the picturesque Petrov. The main entrance glass hall is adjacent to Europoint. Public facilities are located in the front station area. North of Europoint, it is a smaller building with the function of start-up workshops and offices. Towards the river there are the pre-station square and the public transport terminal. The last building is a hotel with leisure activities. The end of the pre-station area by the river is designed with a park arrangement. It is important to connect to the bike path leading along the river. The river is widened at this point and a smaller accessible island is inserted into it. The new railway body is determined by the binding base of SŽDC, which contains the track on the embankment and on the bridge structure at the level of 7,1 meters above the level of the surrounding terrain. The solved part is bounded by two embankments, which will probably be created as massive reinforced concrete walls. The bridge structure lying between these embankments has dimensions of approximately 154x368 meters, which corresponds to the area of 8 football fields. The bridge deck will be drawn on columns of the given raster. The basic principle in the design of the new main station is simplicity, readability and functionality.
