Abstract: This paper proposes three feasible schemes to solve the compatibility and interoperability between CBTC and CTCS-2 (including C2+ATO) systems: "dual trackside", "dual onboard" and "compatible onboard", and compares and analyzes the three schemes, and recommends the " compatible on-board ". The onboard software and hardware configuration and trackside equipment configuration of the scheme are described through the compatible onboard system structure diagram. It focuses on the detailed description of the switching scene. According to different running directions, the obtaining of the movement authority (MA) in the switching scene, the onboard-trackside information interaction content, temporary speed restriction (TSR) and the MA control area, the issuing time of switching information, the arrangement principle of trackside equipment, the operation mode in switching failure, and the operational requirements for drivers, etc. are analyzed in detail.
