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.
