港铁沙中线大围至红磡段完成铺轨

2017-08-21 10:41:52   中国青年网

全长11公里的沙中线大围至红磡段已顺利完成路轨铺设工程。港铁供图

据香港《文汇报》报道,港铁沙中线工程目前进展顺利,港铁公司20日公布,全长11公里的大围至红磡段路轨已经铺设完成,全段东西走廊轨道顺利接通,且追回因考古及保育工作所造成的11个月滞后进度的措施也渐见成效,现正按计划朝着2019年中通车的目标迈进。

沙中线大围至红磡段的路轨来回总长22公里,共重逾2500吨,相等于14架珍宝客机的重量。港铁公司总经理-沙中线及机电工程总管李子文指出,大围至红磡段的路轨铺设工程于2015年9月开展,工程团队由运送钢轨、焊接、铺设路轨枕至测量等每项工序,均规划得一丝不苟,严谨执行每个细节,令路轨能精准地安装和连接。

东西走廊工程进度理想

李子文表示,随着轨道铺设工程完成,下一阶段的轨道工程已经展开。工程车现时在大围站至红磡站之间行走,协助安装各项机电设备,包括架空电缆、通讯设施及信号系统等。预计当所有相关工序完成后,随即展开供电系统及列车测试工作。

他坦言,沙中线工程挑战重重,例如土瓜湾站的考古工作和保育方案,为大围至红磡段工程带来11个月的滞后,但追回进度措施现已渐见成效。

为连接西铁线及马鞍山线,李子文指出,东西走廊的测试工作将牵涉相当复杂及不同范畴的新旧系统,需与营运中的铁路系统反覆调试。为确保营运中的铁路服务不受影响,部分工程及动态测试,更需于凌晨争分夺秒进行。

他续说,现时沙中线东西走廊的整体工程进度理想,港铁会继续谨慎施工,朝着2019年中通车的目标迈进。

总长54公里 全港最长铁路线

沙中线大围至红磡段将马鞍山线由大围站经东九龙延伸至红磡站,接驳西铁线形成东西走廊。

这条连接马鞍山线和西铁线的新铁路走廊,总长达54公里,共有27个车站,将成为全港最长的铁路线。日后乘客不需转线,便可直接往来新界东西。

至于6公里长的沙中线另一段红磡至金钟段,将东铁线延伸至金钟,形成南北走廊,有关工程已于2012年7月展开。

港铁于本月初公布公司中期业绩时指出,由于会展站工地延迟移交,令红磡至金钟段的完工日期延误9个月,但目前仍以2021年为完工目标。

至于沙中线造价的最新估算,港铁早已表明,由于受到不少外在因素包括考古发现、会展站迟交工地等影响,造价估算将显著上升,港铁会于下半年向特区政府提交。沙中线早年通过的整项工程费用为798亿港元。(高俊威)
