Geometry variation of ballasted railway tracks due to weather conditions

Purpose. Investigate and establish the relationship between track geometry measurements weather conditions to determine parameters that influence lifetime of railway tracks’ superstructure system. The study ballasted beds tracks is very important for operation maintenance in case main lines, industrial sidings mine transport. Methodology. Determination annual load selected section based on regulations. Compari made by TrackScan 4.01 instrument different seasons temperatures. Among measured instrument, gauge, alignment, longitudinal level, superelevation are considered analyzed this article.Since lines’ traffic permanently loaded with passenger freight transport used production process, examinations can only be done tramway during standstills at night. results these measurement help understand identify mainlines, mining tracks. Findings. change average values geometrical analyzed, considering typical conditions. Based results, there an evident connection evaluated Originality. Finding changes basis evaluation taken every third month. Practical value. then as input data determining service life tramways,
