“拔罗卜又疼又叫什么病”天津津滨轻轨9拔罗卜又疼又叫什么病号线新信号系统投用 工期刷新全国最快纪录

  中新拔罗卜又疼又叫什么病网天津12月22日电 (记者拔罗卜又疼又叫什么病 周亚强)记者从天津轨道交通集团获悉,22日,津滨轻轨9号线新信号系统投入使用。该新信号系统改造工程于2023年11月启动,采取不停运改造方案“无感”施工,历时13个月,创造了国内地铁信号系统更新改造工程单位里程工期0.25月/公里的最快纪录。

  地铁信号系统是保障地铁列车安全、高效运行的关键系统,相当于指挥列车运行的“中枢神经”。据悉,12月22日凌晨,津滨轻轨9号线顺利完成新旧信号系统一次性倒切。新信号系统使列车正线最小追踪间隔能力由原来的150秒缩短至90秒,行车保障能力显著提升,同时解决了后期维护成本高、技术服务受限等问题,实现轨道交通核心装备“自主化”。

  据了解,新系统通过压缩列车全周转时间、优化调整场段出车路径等举措,在上线列车数量不变情况下可实现工作日早晚高峰增开13列次,行车效率进一步提升。同时,新信号系统下,9号线全线新增5处列车始发点位,始发车站增至13处。实现开往东海路方向的直沽站、中山门站等16座车站,开往天津站方向的市民广场站、泰达站等8座车站的首班车时刻提前,进一步满足民众早间出行需求。

  此外,新信号系统助力津滨轻轨9号线早晚间直达快车再次提速,天津站站至塘沽站单程时间缩短至36分钟,直沽站至塘沽站单程时间缩短至30分钟,“津滨”双城往来乘客出行更加快捷,并实现了与京津城际末班列车的换乘。

  据悉,津滨轻轨9号线于2004年3月28日开通试运行,至今已服务6.7亿人次乘客安全出行,行驶里程8590余万公里。(完)
