摘　　要：针对既有铁路枢纽内C0站与C2站区间闭塞制式为自动站间闭塞、区间无轨道电路及C0/C2等级转换应答器设于C2站进站接近区段,在维持不修改C0站信号系统的情况下,研究提出C0级与C2级相互转换的技术方案。该方案可极大减少工程量和建设投资,保障不同列控等级车载设备的安全平稳转换,一定程度上提高运输效率。The study focuses on C0 stations and C2 stations in railway hubs(with no section track circuits)that operate with automatic inter-station blocking and C0/C2 level transition balises in the approach section of C2 stations.The technical scheme of C0/C2 level transition is studied without modifying the signaling systems of C0 stations.The scheme can greatly reduce engineering workload and construction investment,ensure the safe and stable transition between different levels of train control onboard equipment,and improve transportation efficiency.
