In order to explore adhesion behavior of wheel/rail under the track ramp conditions, the wheel/rail contact of ascent and descent tracks has been achieved by means of clamp change of simulation wheel. The adhesion experiments of wheel/rail were carried out using a JD-1 wheel/rail simulation facility under dry and water conditions. The results indicate that the adhesion coefficient of wheel/rail of ramp track has a significant fall compared with the level track condition under dry and water conditions. The ascent and descent tracks have some differences of adhesion coefficient under the same track gradient condition due to different wheel/rail interaction. Furthermore, the adhesion coefficient of descent track is smaller than that of ascent track under the dry and water condition. Oil contamination is a significant factor on the adhesion behavior of wheel/rail interface. Furthermore, the ramp track has no obvious influence on adhesion coefficient of wheel/rail under oil condition.
