| Abstract: | In order to save time and costs,a new extensible safety platform is proposed for im-proving the functions of the existing CTCS 2/3 train control system without changing it.The ex-tensible safety platform has a double 2 out of 2 structure.Clock synchronization is used for real-time self-test and mutual test between the dual CPUs inside the platform,greatly improving the safety,reliability and availability of the extensible safety platform.. |

| Keywords: | Extensible safety platform Double 2 out of 2 structure Clock synchronization |
