THE SIGNIFICANCE OF THE RAIL LIFTING WAVE

Josef Eisenmann

Open publisher page 3 citations

Abstract

Track buckling, which may arise at high temperatures under a train, originates in the zone of the lifting wave of the rail developing before and behind a wheel set of a vehicle. The lifting wave is considerably influenced by the type of vehicle and the modulus of subgrade reaction of the permanent way. On the basis of a technical examination, it is shown that the lifting wave critical for the track bed stability and ballast stress may be reduced by increasing the weight of the track panel.
