摘要
以上海轨道交通21号线为例,从信号专业的角度,明确满足快慢车混合运行“越行站越行线停放故障车”的具体行车运营需求;结合工程实际,重点分析在该运营需求下,信号系统对越行站越行线有效长度的设置要求;着重讨论依据该需求衍生的“越行线阻塞运营调整”和“越行线单点计轴受扰”2个运营场景,旨在为其他快慢线线路关于越行站轨旁信号系统布置设计方案提供参考。
Taking Shanghai Rail Transit Line 21 as an example,the specific operation requirement of parking faulty train in the overtaking siding at the overtaking station in mixed operation of express and local trains is analyzed in the viewpoint of signaling system.Combined with actual project,the effective length of overtaking siding at the overtaking station in mixed operation of express and local trains is discussed to satisfy the requirement of signaling system.Especially,two ensuing operation scenarios of"operation adjustment about overtaking line blocking"and"single axle counter disturbed of overtaking line"are discussed in hope of providing reference for trackside layout design of the signaling system in other rail transits in mixed operation of express and local trains.
