Abstract: In the Guangzhou-Shenzhen-Hong Kong Express Rail Link project, an advance starting signal SZ is specially installed at the forward departure exit in down direction throat area of West Kowloon Station (WKT) in order to meet the demands of only one train running in the ventilation area and a 3-minutes interval between trains. Since the throat area of this station is relatively short, the setting of the signal has impacts on the interlocking logic of the arriving and departure route as well as the shunting route of this departure exit. In this paper, an in-depth analysis of these effects is carried out, and the problems of route segmentation and switchless shunting route are solved by controlling the nature of segmented route, adding special interlocking relation checks, adjusting the timing of shunting signal at stop and section unlocking mode, etc. The use of the scheme not only meets the operational requirements, but also ensures safety and efficiency.
