EFFECT OF BALLAST CONDITIONS ON TRACK STABILITY

It is shown how installation of long-welded rail on Europe's principal trunk routes has created problems of track stability caused by the presence of thermal stresses in the track, affected by local climatic conditions. The measurements obtained by the tests conducted at the Technical University in Munich, West Germany showed that the lateral resistance is greatest when the track has settled under traffic. After tamping combined with a rise of 2 to 3 cm, the lateral resistance decreases by approximately 70%.
