据央视报道，西安至延安高速铁路（西延高铁）的联调联试工作已全部完成，11月17正式进入试运行阶段，全线开通运营进入倒计时。 打通革命老区交通瓶颈 早在2016年，《国家中长期铁路网规划》发布，西延高铁就被纳入规划中，成为包（银）海通道的组成部分。然而，这条线路从规划之初，就注 定是一段不平坦的旅程。 西延高铁北起关中平原的西安，一路向北，穿越黄土高原的千沟万壑，最终抵达革命圣地延安。一路上，地形复杂，地势险峻，桥隧比高达 91%，这意味着线路中超过九成的线路，不是架在桥上，就是穿在山洞里。施工难度之高，在国内高铁建设中都属少见。 面对如此巨大的工程挑战，为何还要不惜代价，去建这样一条高铁？ 这既是出于补齐交通短板的现实需要，更源于推动革命老区振兴发展的战略考量。 作为革命圣地，延安在政治版图上拥有无与替代的地位，但在经济地理层面，却长期受困于闭塞的交通条件。延安地区以高原、丘陵为主，交通 条件十分不便。以前，从西安前往延安，动车需要两个半小时，通勤效率十分低下，严重制约了区域间的人流、物流与产业协作。 西延高铁全长299.8公里，设计时速350公里，开通运营后，西安到延安的出行时间，将从目前的2.5小时缩短至 ...
