FIELD: railway transport; railway bed condition checking facilities.
SUBSTANCE: cross level of track and forces acting onto left-hand and right-hand axle boxes of wheelsets are measured when each of four wheelsets of track-measuring car pass fixed points of track. Basing on obtained information, average rigidity of track in said points and deviation of rigidity of rail lines from average value of track rigidity are determined using analytical relationships.
EFFECT: possibility of measuring rail track rigidity by track-measuring car at any running speeds.
