空载试运行主要是对车辆、供电、信号、通讯等系统进行全面测试和校验完善，同时对人与设备、系统与系统之间进行充分磨合，通过不少于3个月的空 载试运行、按图试运行、竣工验收、运营评估后，线路才能开通运营。 今年年初发布的北京年度轨道交通建设计划中，18号线的后厂村站——天通苑东站段力争年底开通。而此次海淀区发布的18号线空载试运行的线路图中， 是从起终点马连洼站至天通苑东站。 源自地铁13号线拆分的地铁18号线，是连通海淀北部、昌平"回天地区"的重要线路，也是众多沿线居民非常关注的。 来自海淀区住建委的消息，近日，地铁18号线已经开始为期不少于3个月的空载试运行，为实现年底具备开通试运营条件的目标奠定了坚实基础。 地铁18号线来自于正在进行的13号线扩能提升工程。从昌平区天通苑东站至海淀区马连洼站，这一段连接了海淀北部的大型居住区、中关村软件园、昌 平"回天地区"，是北京北部东西向的骨干线路。 目前我们了解到的，马连洼站正在抓紧建设中，争取能"赶上"一起开通，所以目前还不能"打包票"。 据介绍，此次空载试运行的地铁列车是北京地铁最轻的4动2拖6B编组列车，最大载客量2016人，最高运行速度80km/h，车辆比既有1 ...
