Abstract：Research purposes: The Chinese Railway Specifications says the successive route of receiving has to be set when there is a 6‰ descending grade in the range of braking distance out of the home signal to prevent side collision accident in case that train overruns the start signal．But setting successive route decreases the station carrying capacity and increases the investment．This paper discusses the issue Otl whether Or not to set the successive route for 6‰ descending grade on passenger dedicated line and gives the possibility of not setting the successive route for 6‰ descending grade on passenger dedicated line for providing the reference．
Research conclusions: Through analyzing the reasons for setting the successive route for 6‰descending grade and the sophistication of the braking capability and control equipment of the train running on passenger dedicated line，the idea is expressed in this paper that it is unnecessary to set the successive route when there is a 6‰ descending grade on passenger dedicated line．This idea breaks through the regulation of The Chinese Railway Specifications，but has significance to decreasing the investments in the railway track and signaling equipments，reducing the land occupation and enhancing the traffic capacity．
