在北京轨道交通三期建设规划的各条线路中，亦庄线至5号线、10号线联络线虽然开启动作较晚，但进 展速度却很快。 近日，市发改委批复了亦庄线至5号线、10号线联络线工程项目的可行性研究报告，可研的批复是一项 工程开工前重要的环节，意味着这条线路距离开工已经不远了。 同时，京投公司官网今天也公示了亦庄线至5号线、10号线联络线工程的环评报告全文，其中表示，该 工程初步计划今年年底开工，2028年12月建成。 1 亦庄线目前是在宋家庄站与5号线、10号线三线换乘，因此宋家庄站也是北京轨道交通路网中换乘量最 大的车站之一。 但如果乘坐亦庄线想继续向北，那就要从亦庄线下车，换乘5号线。如果想去国贸、西三环等地，则要 下车换乘10号线。这多少都会给乘客带来不便。 而亦庄线至5号线、10号线联络线工程要解决的就是这个问题。 环评报告估算，在亦庄线和5号线贯通运营后，每天宋家庄站约7.1万人次可以不用再换乘。 而且由于10号线西向东方向与亦庄线、5号线贯通线的南向北方向是同台换乘的，因此3.6万人次将从原 来要步行150米换乘，改为了更便捷的同台换乘。整个宋家庄站日均将有17.1万人次的乘客因此受益， 占宋家庄站日均换乘总量约 ...

Core Viewpoint - The construction progress of the Beijing Rail Transit Phase III plan is accelerating, with the second environmental impact assessment (EIA) for the Yizhuang Line to Line 5 and Line 10 connection being publicly announced, indicating a planned start of construction by the end of this year and completion by 2028 [1][5]. Group 1: Project Details - The EIA report details the specific route of the new line, which will connect the Yizhuang Line at Xiaocun Station to Line 5 at Songjiazhuang Station and Line 10 at Chengshou Temple Station, addressing the inconvenience of transferring for passengers [3]. - The connection line from Xiaocun Station to Songjiazhuang Station will be approximately 2.7 kilometers long, consisting of 2.2 kilometers of new underground construction and 0.5 kilometers utilizing existing lines, with no new or expanded stations being built [3][5]. - The project is expected to have a maximum operating speed of 80 kilometers per hour, with train configurations consistent with the Yizhuang Line and Line 5, using six-car B-type trains [5]. Group 2: Timeline and Impact - The project is planned to start construction by the end of this year and aims for completion by June 2028, which would be an early start compared to the initial annual construction plan that did not include this line [5]. - The connection will significantly benefit residents along the route by improving transit options and reducing transfer inconveniences [5].

Core Viewpoint - The construction of the Yizhuang Line to connect with Line 5 and Line 10 is a significant development for residents in the southern region of Beijing, enhancing convenience and reducing transfer inconveniences at major interchange stations like Songjiazhuang [1][4]. Group 1: Project Overview - The Yizhuang Line to Line 5 and Line 10 connection project has begun its first environmental impact assessment (EIA) public announcement, indicating progress in the planning phase [1]. - The project will span approximately 2.7 kilometers, starting from the existing Xiaocun Station to Songjiazhuang Station [4]. - The initial EIA does not provide detailed route plans or diagrams, leaving the final route configuration uncertain until the second EIA [4]. Group 2: Operational Improvements - The project aims to facilitate through operation between the Yizhuang Line and Line 5, while optimizing transfers with Line 10, thereby improving overall passenger experience [5]. - The integration will occur in two phases: the first phase will align the signaling systems of the Yizhuang Line and Line 5, allowing for flexible train operations during peak hours to alleviate congestion at Songjiazhuang Station [5]. - The second phase will implement through operation with Line 10 once its equipment reaches the end of its service life, further enhancing connectivity [5].
