如何测试高铁是否平稳?只要掏出一枚硬币,在行进中的列车内,看它能不能立起来。

作为四川第一条动车,2010年5月12日开通的成灌快铁,如今已经立不起硬币,开通运营7年后,成灌快铁轨道尺寸出现偏差,正在进行首次大修。

成灌快铁从主城区到都江堰、青城山和彭州,周末上座率超过80%,每天开行64趟次,已经深度融入成都市民的生活。8月25日凌晨,华西都市报-封面新闻记者来到成灌快铁郫县西站至安德站区间,见证成灌快铁开通7年来首次大修。

成灌快铁2010年5月12日开通,总长约91公里,沿线设车站20个。作为成都城区连接都江堰、彭州、青城山的一条市域快速铁路,投用以来,每天早晚高峰和周末上座率都在80%。

其中,犀浦高铁站是成灌快铁往都江堰、彭州、离堆公园方向的枢纽车站,由于接驳成都地铁2号线,成为旅客换乘主要车站。截至目前,犀浦高铁站的日均到达、发送客流在1.1万人左右。

今年暑期全国铁路运行图调整后,成灌快铁每天动车开行增加到了64趟次,7月23日,成灌快铁在犀浦站实现全国首例动车、地铁同台无缝交互换乘。

25日凌晨0点10分,绝大多数人已进入梦乡,在成灌快铁郫县西站至安德站区间,71名快铁工务人员才正式开工,他们被称为高铁医生,由于一场中雨,原定于11点半开始的检修被迫推迟,确定不再下雨后才正式开始。

列车白天运营,检修只能在晚上进行,成灌快铁本次大修从今年6月开始,每天晚上11点半列车停运,直到凌晨4点半,这便是他们的工作时间。

成都铁路局成都高铁工务段成都西线路车间主任李坤说,成灌线开通运营7年后,存在线路设备老化较严重、部分铁垫板下弹性垫板弹性衰减、充填式垫板老化失去弹性等问题。
