    "body": "## 概况\n\n北京地铁1号线支线列入北京市轨道交通第三期建设规划（2022—2027年）。线路西起房山区青龙湖东站，北至石景山区八角游乐园站，在八角游乐园站接轨既有1号线，可与1号线主线直通运转。全长约21公里，均为地下线，共设车站10座，其中新建9座、改扩建八角游乐园站1座，并设王佐停车场。[^wiki-zh]\n\n2024年1月18日，1号线支线工程正式进场施工，是北京市第一条下穿永定河的轨道交通线路。[^wiki-zh]北京市“十五五”时期现代综合交通运输体系发展规划将1号线支线列入“十五五”期间建成项目。[^plan-15th]\n\n## 车站与换乘\n\n车站自北向南为：八角游乐园、体育场南街、园博园西门、张郭庄、西二区、后吕村、云岗、王佐、民族大学、青龙湖东。其中张郭庄站换乘14号线，体育场南街站换乘规划中的11号线二期，后吕村站换乘市郊铁路副中心线。2025年7月，8座新建车站站名命名预案公示，体育场南街、西二区、云岗、民族大学四站拟分别改称衙门口西、北宫、飞航云岗、魏各庄。[^wiki-zh]\n\n为配合支线施工，八角游乐园站自2025年6月2日起封站改造。[^wiki-zh]园博园西门站施工占道措施见于北京市公安局交通管理局通告。[^s743913598]\n\n## 车辆\n\n支线采用B型车6辆编组，设计最高速度80公里/小时。按环境影响评价报告书，支线计划于2027年建成。[^wiki-zh]",
