Restoration of lines of rails by welding and elimination of expansion joints is necessary.
Keywords:Line of rails, joint gap, place of temporary restoration, temperature of rail, temperature force, leveling place, long-welded rails, fastening down temperature, fish bolt.
Supervisions over temporary rail inserts and leveling places of long-welded rails, proving insufficient compensation of temperature forces in lines of rails are given. The conclusion about necessity of immediate welding of places with temporary rail inserts and elimination of leveling places is drawn.
