Track smoothness

High track smoothness in railway traffic is a requirement for reaching high speeds safely. The freezing of the ground changes the shape of the ground surface, displacing the tracks. Snow packing under the rails elevates them unevenly, when one part of the track is elevated more than the adjoining parts. Because of this, the track smoothness is lowered.
