Abstract: Form design of platforms is an importance part of urban rail transit planning and construction. In this paper, the characteristic of Songjiazhuang Station of Beijing Yizhuang subway are studied. Based on it, three forms of platform design, such as one-island-two-side with two lines, one-island-one-side with two lines, and one-island-one-side with three lines, are expatiated. Then, this paper compares the waiting conditions, back-turning capacity, conditions of sections for leaving and arriving and the station dimensions of the three forms. From point of the impact factors to frontal back-turning capacity of island-platforms, as well as the impact of the platform passenger organizing program to platform’s width and train stopping time, this paper drawns a conclusion that the one-island-two-side with two lines platform suits the original stations of urban rail transit with island-platform and frontal back-turning section.
