Abstract：Abstract ： Research purposes ： The avoiding of hard rolling wagon colliding with easy rolling wagon and vehicle coupling at a high speed are considered in hump design specification，and the train operation performance and vehicle operation safety is neglected. At the same time， the method that designing slope after confirming hump height was proposed in hump design code not only confines the hump geometric design flexibility，but also limits the slide efficiency. Based on railway line parameters of a hump and train operation performance analysis， taking vehicle humping safety as the premise，length of the accelerate slope was optimized in this research. Research conclusions: (1) The regulated accelerate slope length in existing standard can ensure the humping safety. (2) The enhancement of vehicle humping speed is restricted for the regulated accelerate slope length in existing standard. (3) The selection slope can be increased suitably according to the hump level and the terrain conditions to enhance the humping efficiency of hump.
