The work represents the results of three-year twenty-four-hour topoclimatic measurements of temperature options at Lviv–Mukachevo railway stations in order to clarify the influence of temperatures on rails transformation, the road and the railway embankments as factors of activating deformation and destructive processes.In the first approximation, daily and seasonal fluctuations of temperatures at different localities of the railway were clarified. It was calculated that the railway works in terms of range of the temperatures and rails from minus 35 to 65°C.The maximum amplitude of temperatures can be formed at the Precarpathians in conditions of stagnation and local transformation of sedentary air masses that can cause the greatest changes in the region compared to the whole railway.That is why this section of the railway requires more careful examination and proper execution of work in stabilization of road safety.Key words: the railway, topoclimate, linear thermal expansion of steel, twenty-four-hour registration, temperatures range, processes of transformation.
