清晨6点，黑龙江哈尔滨站的站台上，动车组列车准点发车，驶向齐齐哈尔。 列车行驶在哈齐高铁线上。 原 勇摄（新华社发） 8月17日，我国最北高寒高铁哈齐高铁迎来开通运营10年。10年间，哈齐高铁累计安全运行超8189万公 里，运送旅客超1亿人次。 2015年开通运营的哈齐高铁，覆盖黑龙江省半数人口、六成经济总量，将哈尔滨至齐齐哈尔的旅程从5 小时压缩至1小时24分。从初期每日20对动车组，加密至54对。 "在哈尔滨品西餐，在大庆吃坑烤，到齐齐哈尔直奔烤肉店。"北京游客陈宇星展示着社交媒体推荐 的"高铁美食地图"。哈齐高铁不仅拉近了时空距离，更激活了沿线冰雕雪塑、石油研学等特色资源，促 进了人才流动与产业融合。 在冬季平均气温低至零下30摄氏度的极寒环境中，列车如何以250公里时速行驶？破冰前行，离不开科 技护航。 清晨，齐齐哈尔供电段工长申宇航登上综合检测车"试跑"全线。"车上搭载的供电安全检测监测系统， 每秒能拍下17张高清照片。"申宇航调出一组标记着"极寒天气"的组图介绍，"接触网上微小的冰凌、螺 丝的细微位移，都逃不过它的'眼睛'。红外探伤像B超一样，精准发现因极寒产生的细微隐患。"这些冬 季积累的"病例 ...
