This thesis presents railway track components, track measuring and analysis of track components and it’s influence on track degradation.
First part of thesis presents degradation of track and description of track components. Special requirements that are defined by standards and regulations are described for each track component.
Second part of thesis presents measuring trains that do measuring on Slovenian railway system. Measuring trains that are represented can measure conditions of rail and conditions of track. This part also describes the regulations for measured parameters that are required with Pravilnik o zgornjem ustroju železniških prog (2010).
The last part of thesis describes the analysis of measured parameters on railway line number 50 Ljubljana–Sežana–d.m. between Ljubljana and Postojna. The geometry and other characteristics of line no. 50 from Ljubljana to Postojna are represented. The effects of superelevation, lateral acceleration and curve radius on track gauge are represented. It is checked how the average track gauge, rail twist and settlements develop depending of curve radius.
