Abstract：Abstract：Research purposes： By using systemic analysis method,this paper, focuses on the technical issues between track-layout and signal system, such as system matching design, station effective length of track & platform settings, catch siding, successive route, turnouts in receiving-departure track, and turnout-settings in station etc. The contents and conclusions, which researched, are of positive significance not only in the quality improvement of railway track-layout and signal interface design, but also in the enhancement of the systemic railway engineering design.
Research conclusions：(1) The turnouts on which CTCS-0 is employed should not be the one with turnout number greater than 18#. The turnouts where CTCS-2 control system is adopted should not be the one with turnout number lower than 9#. (2) In case the distance between track center line and edge of platform is 1 750 mm, the speed limit of the main line should be set below 80 km/h, and correspondingly, the design of the turnouts and the tracks within station should be in line with the speed limit of train control system.(3)The effective length of passenger station track, the position and length of platform, and the locomotive stop location mark should take reasonably consideration into the starting signal, fouling post, balise and so on, which should be in line with the technical requirements of train control system. When it is difficult to meet the normal technical requirements in terms of the platform length and effective length of passenger station track due to the geographic and geomorphic conditions, special signal solution should be considered. (4) The position of catch siding should not be far from the intersection of the two lines extra safety methods such as "red light" or other train control measures combining with necessary traction simulation should be adopted to satisfy the requirements of safety and efficiency.(5) A conversion slope outside the home signal within the braking distance should not be greater than 6 per thousand as far as possible. If the conversion slope is greater than 6 per thousand, measures should be taken to satisfy the requirements of interval time design.(6)The turnouts layout for railway stations with more than two main lines should satisfy the installation requirements of movable switch machine.(7) The turnouts arrangement in CTCS-2/CTCS-3 section should consider the insulation joint settings of track circuit.(8) This paper can provide references for the interface design of railway track layout and signaling.
