Beijing-Tangshan Railway and Beijing-Harbin Railway Realize Merging and Intercommunication

4月25日上午7时，京唐铁路北京段第二组42号道岔横移并入既有京哈铁路下行线。至此，京唐铁路上下行线路横移并入京哈线施工全部完成，京唐铁路与京哈铁路并轨互通，为京唐铁路如期开通奠定了基础。

At 7:00 a.m. on April 25th, the switch No.42 of the second group of Beijing section of Beijing-Tangshan Railway moved horizontally and merged into the existing down line of Beijing-Harbin Railway. So far, the construction of traversing the up and down lines of Beijing-Tangshan Railway into Beijing-Harbin Railway has been completed, and the Beijing-Tangshan Railway and Beijing-Harbin Railway have been merged and interconnected, which has laid a foundation for the opening of Beijing-Tangshan Railway as scheduled.

据京津冀城际铁路投资有限公司所属京唐城际铁路有限公司相关负责人介绍，42号道岔是目前国内高铁既有线插铺施工型号最大、长度最长的高速道岔，代表了当前我国道岔的最高技术水平。此次插铺的42号道岔长157.2米，总重量达232吨，横移距离为7.7米。通过插铺道岔，使机车车辆从一个股道转入另一股道，进而实现线路之间互相联系。42号道岔能够大大缩短列车转线时间，提高通行效率。

According to the relevant person in charge of Jingtang Intercity Railway Co., Ltd., which belongs to Tianjin Intercity Railway Investment Co., Ltd., No.42 turnout is the largest and longest construction type of existing high-speed railway line in China at present, which represents the highest technical level of turnouts in China at present. The switch No.42 turnout inserted this time is 157.2 meters long, with a total weight of 232 tons and a traverse distance of 7.7 meters. By inserting and laying turnouts, locomotives and rolling stock can be transferred from one track to another, thus realizing the mutual connection between lines. Turnout No.42 can greatly shorten the train transfer time and improve the traffic efficiency.

京唐铁路起自北京城市副中心站，经北京市通州区、河北省廊坊市、天津市宝坻区、河北省唐山市，终至既有唐山站，正线线路全长约148.7公里。全线共设置车站8座，分别为北京城市副中心站、燕郊站、大厂站、香河站、宝坻南站、鸦鸿桥站、唐山机场站、唐山站，最高设计时速350公里。截至目前，京唐铁路全线路基、桥梁主体工程已基本完工，铺轨工程进入尾声，站房工程即将全部封顶，正在加紧施工，四电工程基本准备就绪。

Beijing-Tangshan Railway starts from Beijing City Sub-center Station, through Tongzhou District of Beijing, Langfang City of Hebei Province, Baodi District of Tianjin and Tangshan City of Hebei Province, and finally to Tangshan Station of Hubei Province. The length of the main line is about 148.7 kilometers . There are 8 stations in the whole line, namely Beijing City Sub-center Station, Yanjiao Station, Dachang Station, Xianghe Station, Baodi South Station, Yahongqiao Station, Tangshan Airport Station and Tangshan Station with a maximum design speed of 350 kilometers per hour. Up to now, the main works of subgrade and bridge of Beijing-Tangshan Railway have been basically completed, the track-laying project has come to an end, the station building project is about to be capped, the construction is being stepped up, and the four power projects are basically ready.

京唐铁路是落实京津冀协同发展战略，推进京津冀交通一体化率先突破的标志性工程，项目建成后将打通北京至唐山城际通道，极大提升通道运输服务能力，进一步带动沿线地区经济发展，有力促进京津冀区域互联互通。

Beijing-Tangshan Railway is a landmark project to coordinated development strategy of Beijing-Tianjin-Hebei and promote the integration of Beijing-Tianjin-Hebei transportation . After the completion of the project,it will open up the Beijing-Tangshan inter-city corridor, greatly enhance the transportation service capacity of the passage, further drive the economic development of the areas along the route, and vigorously promote the regional interconnection of Beijing-Tianjin-Hebei.
