China News Service, Shenyang, December 1 (Reporter Yu Haiyang) On December 1, 2022, the world's first alpine high-speed railway, the Harbin-Dalian high-speed railway (hereinafter referred to as "Harbin-Dalian high-speed railway"), opened for 10 years.
In the past 10 years, the Harbin-Dalian High-speed Railway has safely operated 739,000 multiple trains, with a running mileage of 671.17 million kilometers and transported more than 670 million passengers.
It provides safe, high-quality and efficient transportation guarantee for passenger travel and regional economic and social development.
The Harbin-Dalian high-speed railway runs through the three provinces of Heilongjiang, Jilin, and Liaoning. It is located in the alpine region along the line, with frequent rain, snow and freezing weather in winter.
After exploration and practice, China Railway Shenyang Bureau Group Co., Ltd. (hereinafter referred to as "Shenyang Bureau Group Company") has formed a set of safe operation organization system to cope with severe cold and ice and snow weather, established a meteorological disaster early warning and forecast system, and improved ice and snow early warning and disposal Measures, implement hierarchical management of snow removal and deicing of turnouts, adopt heating and melting of turnouts, driving at intervals, manual snow removal and other methods according to the level of snow volume, to ensure the safety and smooth flow of high-speed railways.
Since the opening and operation of Harbin-Dalian high-speed railway 10 years ago, a total of 588 snowfalls have occurred on the whole line, with an average snow depth of 67 mm. Relying on strict organization, scientific scheduling and effective command, it has ensured that trains of high-speed trains can safely cross the ice and snow, and meet the travel needs of passengers to the greatest extent.
Transportation security continued to be stable.
As the world's first alpine high-speed railway, the maximum temperature difference between winter and summer along the Harbin-Dalian high-speed railway is nearly 70°C.
After years of independent exploration and innovation, the Shenyang Bureau Group Company has fully mastered the operation and maintenance technology of the alpine high-speed railway without any experience in forming.
On the train, the constant temperature of the entire train compartment has been realized, overcoming the problem of low temperature at the joints of the compartments and near the doors; on the line, the problem of "frost heave" control of the subgrade of the railway in the alpine area has been overcome, and "one operating diagram in winter and summer" has been implemented. It runs at a speed of 300 kilometers per hour throughout the year; in the low-temperature adaptability technology of equipment such as traction power supply and communication signals, it has formed the core technology system for high-speed railway operation in alpine regions; in terms of driver control, it has summarized and promoted effective measures for driving in ice and snow weather, Ensure that high-speed rail trains are safe, punctual, stable and comfortable.
In addition, Shenyang Bureau Group Corporation also used the world's largest high-speed ballastless turnout at Changchun West Station, breaking through the technical bottleneck that restricts the speed of high-speed trains entering and leaving the station.
Over the past 10 years, the Harbin-Dalian high-speed railway has formed a safety management system integrating infrastructure, mobile equipment, comprehensive testing, disaster prevention and mitigation, and emergency rescue. The gap in high-speed rail technology ensures the safe and orderly operation of the Harbin-Dalian high-speed rail.
Service quality has been continuously improved.
Since the opening and operation of Harbin-Dalian high-speed railway 10 years ago, Shenyang Bureau Group Corporation has always practiced the service tenet of "people's railway for the people", adhered to the concept of "Internet +", introduced intelligent equipment and facilities, and improved the level of scientific and technological services.
Electronic tickets are fully implemented, and passengers can travel freely with "one card in hand"; automatic ticket gates are installed, and the time for passengers to enter and exit the station is shortened from the original 3.8 seconds to 1.3 seconds; mobile phone ordering service is provided, just move your finger, Delicious food can be delivered to the seat; online seat selection service is launched, passengers can choose designated seats according to personal preferences, etc.

Drive the formation of the northeast high-speed railway network.
Since the opening of the Harbin-Dalian High-speed Railway 10 years ago, the Harbin-Dalian High-speed Railway has been formed as the north-south main axis. The north is connected with the three high-speed railways of Haqi, Hamu and Hajia. , connecting the Shenyang-Danzhou, Xintong and other high-speed railways in the south and the railway network of the Danish-Dalian Express Railway, and linking with the Beijing-Shenyang section of the Beijing-Harbin High-speed Railway, integrating into the national high-speed railway network, forming a 2-hour railway centered on Shenyang, Changchun, Dalian and other cities The economic circle, the 4-hour economic circle from major cities to Beijing.
Today, Harbin-Dalian high-speed rail trains have connected major cities in Northeast China, North China, Central China, and East China, and can reach all domestic high-speed rail cities through transit transfers.
The high-speed railway network extending in all directions has greatly shortened the regional space-time distance and shortened the "economic distance" of the region, such as criss-crossing arteries, injecting new vigor and vitality into the revitalization and development of the Northeast region.
Passenger and cargo products were further enriched.
The opening of the Harbin-Dalian high-speed rail not only shortens the distance in time and space, making travel more convenient for passengers, but also activates the potential of tourism projects such as "short-distance travel" and "weekend travel".
Relying on the Harbin-Dalian high-speed railway, the Shenyang Bureau Group Company has successively launched themed trains such as the "Research Special Train", "Flower Appreciation Special Train", "Catch the Sea Special Train" and "Ethnic Customs Special Train" to fully meet the travel needs of passengers and effectively help the revitalization and development of the countryside. People's happy life index.
The opening of the Harbin-Dalian high-speed railway has also effectively released the transportation pressure of the existing lines. The annual freight capacity of the Shenyang-Dalian line has increased by 11.5 million tons, and the annual freight capacity of the Beijing-Harbin line has increased by 10 million tons. The heavy chemical industry in Harbin, the automobile industry in Changchun, Shenyang The equipment manufacturing industry in Dalian, the petrochemical, shipbuilding and high-tech industries in Dalian, and the iron and steel industry in Anshan are the pillar industries distributed along the Harbin-Dalian High-speed Railway.
Since its opening and operation 10 years ago, the Harbin-Dalian high-speed railway has brought more happiness and a sense of gain to the people in Northeast China. Make more and greater contributions to the new journey of modernization.
