2014 Nian 9 26, Beijing-Tianjin inter-city railway by the state.

Line Station

Design Parameters

stations along

intercity railway line total of seven stations, respectively Beijingnanzhan, Serious station ( temporarily for passenger traffic) , Wuqing station, Tianjin station, Junliangcheng North station, Tanggu station, coastal station.

alignments

intercity long railway line 166 km provided seven sites, the eastern end of the lead line from Beijingnanzhan, Jingshan railway along the east after Yuting beneath the bridge to the left along the South moat Yasukado off the southeast, then the eastern side of the Beijing-Tianjin Metro Paradise BDA and second high-speed channel from Beijing, leading to Tianjin station. Extension line project west Tianjin Railway Station, Tianjin Railway Station Intercity yards from the eastern end leads, along both Jingshan railway, Tianjin and Qinhuangdao Passenger Dedicated Line parallel, the Tanggu Railway Station, fold the introduction of Binhai New Area Central Business District to the southeast Jiabao, east coastal stand.

Beijing-Tianjin Intercity Railway Beijing by the China Railway Bureau Group Co., Ltd. is responsible for transportation and management.

the operations of

operator course

August 1, 2008, the Beijing-Tianjin inter-city railway official operation, the initial operating speed of 350 km / h CDB 47 pairs of trains.

2011 in August in accordance with the requirements of the former People's Republic of China Ministry of Railways, Beijing-Tianjin inter-city rail spin-down to 300 km / h run.

starting at 0:20 on the June 2017 day implementation of the new Beijing-Tianjin intercity railway train diagram, increase the opening line density. Weekdays from Monday to Thursday CDB 98.5 pairs of the weekend from Friday to Sunday opening line of 108.5 right.

Since May 27, 2018, the Beijing-Tianjin Intercity Railway first-class seat, the Principal seat fare be raised, fare adjustment does not involve the second seat; the same year July 1, 2018 the railway sector in the second stage of train diagram adjustment, the Beijing-Tianjin intercity railway line to open a total of 108.5 pairs of trains; the same year on August 8, Beijing-Tianjin intercity railway operating speed of the formal resumption of 350 km / h, the CDB the number increased from 108.5 pairs of trains to 136 Yes, and the same fare.

2019 Nian 1 on 5, 26 pairs of high-speed rail trains originating adjusted to Tianjin West Railway Station to Beijing South Railway Station Beijing-Tianjin inter-city Tianjin Railway Station to the final, Tianjin West Railway Station intercity trains originating end to the 35 pairs yujiapu railway station renamed coastal station.

Since 10 December 2019, the Beijing-Tianjin inter-city railway line and the extension of the South involving a total of Beijing, Tianjin, Tianjin West, Wuqing, Tanggu, Binhai, Junliangcheng North Station 7 pilot implementation of e-ticketing service .

Passenger traffic

In 2008, the Beijing-Tianjin inter-city passenger rail sent 6,350,000 passengers.

2013 years, the Beijing-Tianjin Intercity Railway to send visitors 25.85 million passengers.

As of September 29, 2014, the Beijing-Tianjin inter-city railway passenger transport a total of 117 million passengers, an average load factor of 72%.

As of July 1, 2018, the Beijing-Tianjin inter-city railway passenger transport a total of 250 million people.

Equipment Facilities

vehicle facilities

Beijing-Tianjin inter-city railway early use CRH2C EMU by the Qingdao Sifang Locomotive Co., Ltd. designs, and by the Tangshan Railway vehicle Co. Ltd. design and manufacture of CRH3C EMU.

Since April 6, 2009, the Beijing-Tianjin inter-city railway are switching to CRH3 type EMU train.

2018 Nian 8 1st, Beijing-Tianjin Intercity Railway to replace all the renaissance number CR400BF type EMU.

Runtime

Beijing-Tianjin Intercity Railway electronically controlled fully automatic driving system, in bad weather conditions, it is safe to run. Beijing-Tianjin inter-city railway design minimum departure interval is 3 minutes, EMU trains issued by the centralized control system for train running information, on-board radar receive real-time operational data and instructions passed to the on-board computer, automatically adjust the tracking interval between each train, prevent trains speeding and aggressive signals. Line current fault occurs after the train, directly behind the train to slow or stop the information obtained; when foreign objects or broken rail appears on the line, the train operation control system to respond quickly.

construction achievements

technical problem

• roadbed easy settlement

railway soft soil foundation for the Beijing-Tianjin inter-city, soft soil, bedrock at Tianjin in 1000 meters. Such soil with a high water content, high compressibility, poor permeability, low-intensity characteristics, the laying of ballastless track on this type of soil, Chinese at home and abroad is not mature experience. After a series of technical research, Chinese technicians using the enclosed portion wells, reduce or control groundwater exploitation along the route; the bridge increased pile length, pile diameter, the use of adjustable height pedestals; adjustable fastener track to take other measures to effectively control the soft land bridge roadbed deformation and base area of ​​the settlement, to meet the requirements laid ballastless track under the soft ground settlement and regional conditions.

• scarcity of land resources

Beijing-Tianjin Intercity Railway passing through Beijing, Tianjin two municipalities , economic development along the roads criss-crossing the land resources is extremely valuable, is to minimize the cutting of the city railway line, saving valuable land resources, through comprehensive technical and economic comparison, the Beijing-Tianjin inter-city railway widely used alternative to traditional bridge roadbed, bridges length accounted for 87% of the total length of the line, saving an average of 44 acres of land per kilometer bridge, this alone saves more than 1,600 acres of land.

key project

• Liangshui River Bridge

Liangshui River Bridge located in the Tongzhou District of Beijing, it is a Bridge in the Beijing-Tianjin intercity railway. And bridges across the ring road Liangshui, full length 21.563 kilometers, a total of 648 holes, the maximum span of 100 m, the minimum span of 48 m.

• Beijing Ring Road Bridge

Beijing Ring Road Bridge is located in Beijing, Beijing and Tianjin intercity railway bridge across from the Beijing South Railway Station, Beijing area. Since the bridge after termination from Beijing Dongcheng left Tiananmen Square west about 700 meters southeast of continuous cross on two, three, four, Fifth Ring Road and other roads, through Fengtai and Chaoyang District, on the cross road through yellow Town, Tongzhou District in Guangxi Jia fen village. Bridge full-length 15.6 kilometers, the maximum span appears across the tetracyclic, pentacyclic main span, the span were 128 m; cross two, compared with 100 m span girder tricyclic. Beijing Ring Road Bridge on October 13, 2007 closure.

research

2009 years, the Beijing-Tianjin Intercity Railway locomotive works by the Quality Project Award; the same year, the Beijing-Tianjin inter-city railway project by Zhan Tianyou Civil Engineering Prize.

2010 years, the Beijing-Tianjin intercity railway works by the 60th anniversary of the founding of new China, "100 Classic Construction Projects."

2013 January Beijing-Tianjin intercity railway project by China National Science and Technology Progress Award.

Beijing-Tianjin Intercity Railway narrowed the distance between Beijing and Tianjin, two large cities, enlarge the various factors of production, space allocation of resources, for two urban economic and social development had a major impact, but also profoundly changed the concept of life and work of the two peoples, to facilitate the travel of the people. Meanwhile, as China's high-speed railway design speed of 350 km's first, Beijing-Tianjin Intercity Railway not only train a number of Chinese high-speed railway development and construction of the pathfinders, pioneers also provided technical and accumulated valuable experience for the Chinese high-speed rail to lead the world; Moreover, the Beijing-Tianjin Intercity Railway to run a safe and stable, comfortable and fast ride, consumption of energy-saving and environmental protection advantages, promote the great changes in the modes of transportation.
