北京地铁13号线扩能提升工程建成后，将进一步加大北京北部回龙观、天通苑等大型居住组团内部的轨 网密度，串联起既有13号线西段、上地软件园、回龙观、天通苑及13号线东段，改善城市东北部、西北 部原有轨网之间的换乘关系，为市民提供更加快捷、舒适的出行体验。 值得一提的是，在今年的北京市轨道交通开通计划中，其实并没有13号线扩能提升工程。根据规划， 2025年，北京计划开通17号线(工人体育场-十里河)和6号线南延(潞城-东小营南)两条(段)地铁新线。 据北京市重大项目办此前介绍，13号线扩能提升工程计划年底开通后厂村站(现定名为"东北旺站")至天 通苑东站段。记者了解到，这一段线路全长17.1公里，设车站9座，包括换乘站4座。线路采用6B车辆， 设计时速为80公里。建成后，将串联起海淀区后厂村区域及昌平区天通苑、回龙观区域，与8号线、17 号线等地铁线路实现换乘，对完善北部地区轨道交通线网，改善昌平、海淀两区市民出行条件具有重要 意义。 近日，北京地铁13号线扩能提升工程的11座新建和改建车站名称确定并对外发布。相较今年3月发布的 站名预案公示内容，新建龙泽站仍沿用"龙泽站"的老站名，另有两站名称调整，"软件园站 ...
