RESULTS OF TEST ON THE DB'S EXPERIMENTAL WAVY-RAIL SET

Wavy or corrugated rail surfaces have been an unsolved problem for decades, and have given rise to many theoretical and experimental investigations. The aim of the research, which is often costly, is to find out what causes wavy rails and to reduce the extent and intensity of these influences. The results of investigations at the two wavy-rail test set-ups at the DB's Central Office in Munich show that the material of the DB's standard rails--the S 54 and the UIC 60--has no influence, neither in respect of the chemical analysis, nor the internal rail stress, nor the position in the bloom. On the other hand, it appears that the surface roughness of the rail, the coefficient of subgrade reaction, the vibrational behaviour of the whole system, the likewise vibrating mass and the excitation may have a decisive influence on the appearance of wavy rails.
