At 7:50 on August 15, the first group of CR400BF-G-type Fuxing alpine EMU at the Mudanjiang high-speed rail joint test site slowly drove out of Mudanjiang Station. This is the first time that the Fuxing alpine EMU has participated in the Mujia high-speed rail joint commissioning test, and it is also the first time that the Fuxing alpine EMU has been tested on the easternmost alpine high-speed rail line in my country.
The eastern part of Heilongjiang Province is the easternmost part of my country. The cold weather is a relatively big challenge for high-speed rail EMUs. Although the eastern part of Heilongjiang Province is located in the easternmost part of our country, but the special geographical location, the development of its regional economy has a very important strategic significance for our country. The trial run and success of the Fuxing high-cold EMU is of great significance to the opening and operation of the Fuxing high-cold EMU in the future.
It can be predicted that in the future, the operation of Fuxing alpine EMU will bring great development potential to the eastern part of Heilongjiang Province, promote local economic development, as well as people-to-people exchanges and economic development in the surrounding areas.
It is understood that the Mujia high-speed railway is located in the eastern part of Heilongjiang Province, passing through Mudanjiang City, Jixi City, Qitaihe City, Shuangyashan City, Jiamusi City and other places along the line, with a total length of more than 370 kilometers and a design speed of 250 kilometers per hour. It is currently the longest high-speed rail line in Heilongjiang Province. This has brought the foundation for the construction of the urban agglomeration and economic circle of Heilongjiang Province, and has a significant role in promoting the economic development of the eastern region of Heilongjiang Province and the formation of economic synergy.
In addition, the 350-kilometer-per-hour Fuxing high-cold EMU has the "stunt" of low temperature and ice and snow resistance, and can run in an environment of minus 40 degrees Celsius. Being able to resist the impact of low temperature demonstrates the progress and development of my country's scientific and technological strength, and has a good reference significance and experience accumulation for the development of high-speed rail in severe cold areas.
In particular, since the launch of the Mujia high-speed railway joint commissioning test on June 10, the EMU step-by-step speed-up test and the signal system test have been carried out respectively. After the dynamic detection and debugging of the track, communication, disaster monitoring and other systems, the functions of each system and the overall system have been optimized. The preparatory work will be tested in advance, especially for disasters and other unexpected situations, to ensure the safety after opening and operation. It is the greatest respect for science to speed up step by step and avoid the situation that haste makes waste.
The successful trial run of the Fuxing Alpine EMU shows the hard strength of my country's high-speed rail technology. Soon the easternmost end of my country will usher in the official opening and operation of the Fuxing Alpine EMU.
