记者从市交通委获悉，今天起，北京地铁1号线支线启动接轨改造。为配合地铁1号线支线建设，实现其 与既有1号线的贯通运营，1号线古城站、八宝山站同步采取临时封站停运措施，预计持续至2026年5月 底。 施工期间，1号线列车运行区段临时变更为玉泉路站至环球度假区站，在玉泉路站折返运营，公交、地 铁、非机动车联动保障交通出行。届时，1号线苹果园站也将同步完成改造，恢复运营，实现与6号线、 S1线的三线换乘。 1号线支线与既有1号线启动接轨 根据规划，1号线支线与既有1号线的接轨点位于八角游乐园站东侧区间。"由于八宝山站不具备列车折 返条件，为安全高效地进行接轨改造，必须对古城站、八宝山站实施临时封闭。"京投轨道公司第一分 公司1号线支线工程甲方代表孟令东介绍，"此次接轨改造，还需与苹果园站改造、三线换乘系统调试等 工作同步推进。" 据了解，北京轨道交通1号线支线工程，南起青龙湖东站，北至八角游乐园站，线路全长21公里。线路 新建车站9座，改造车站1座（八角游乐园站），平均站间距2.3公里，包括后吕村站、张郭庄站、体育 场南街站3座换乘站。此次封站施工是1号线支线工程的关键节点。 本次改造工程内容包括拆除既有线区间结构 ...

此次改造施工内容包括拆除既有1号线区间结构侧墙，改移通信、信号、机电、供电等光缆，铺设轨道 等。为最大限度减少对1号线运营的影响，市重大项目办会同市交通委，地铁建设及运营单位充分调 研，多次组织国内外相关领域专家咨询会，开展多轮方案研究，完成土建改造、线缆改移及轨道铺设等 关键工程的方案编制与论证，编制了专项施工方案和运营安全专篇，精细筹排施工计划，计划施工总工 期约3个半月，施工时间为2026年2月15日—5月30日。 由于八宝山站不具备折返条件，施工期间，1号线列车将运行至玉泉路站进行折返。古城站、八宝山站 将临时封站停运，乘客需提前规划路径。 1号线支线作为服务石景山、丰台等区域的重要轨道交通线路，目前已进入全面建设阶段，预计2027年6 月具备开通条件。1号线支线与1号线的接轨点位于八角游乐园站东侧区间，通过对接轨点的改造施工， 预计线路建成后将在八角游乐园站与1号线实现贯通运营。 北京商报讯(记者和岳)2月9日，北京商报记者从市交通委、市重大项目办获悉，为配合地铁1号线支线 建设，实现其与1号线贯通运营，自2026年2月15日起，1号线古城站、八宝山站将临时封站停运，列车 运行至玉泉路站折返，预计于 ...
