Zhengzhou, China – September 5, 2024
The heat slide test for the Phase I project of Zhengzhou Metro Line 7 was successfully completed on the morning of September 5, marking another step closer to the completion and operation of the line by the end of the year. The test, which was carried out on the basis of tunneling, rail connection, and electrical connection, signifies the progress of the project.
Line 7 Phase I: An Important Addition to Zhengzhou’s Urban Transportation Network
Line 7 Phase I is a north-south oriented densification line located in the central urban area of Zhengzhou. The line starts at Dongzhao Station and ends at Nangangliu Station, primarily following the routes of Wenhua Road, Youxun South Road, Jinfu Road, and Daxue Road. It consists of 20 stations and 8 interchange stations, connecting with Lines 1, 2, 3, 4, 5, 10, as well as the northeast section of the under-construction Line 6 Phase I and Line 8. The trains are composed of 6 A-type cars, with a maximum operating speed of 100 kilometers per hour.
Heat Slide Test: A Crucial Step in Ensuring Safe Operation
The heat slide test involves the operation of trains on the entire line while the overhead contact lines are energized. This comprehensive test assesses the power supply system, overhead contact lines, track, communication system, signaling system, clearances, and vehicle operation. It is a crucial verification process for safe operation during the construction phase.
Completion of Heat Slide Test Paves the Way for Subsequent Testing and Operation
The successful completion of the heat slide test means that the Phase I project of Zhengzhou Metro Line 7 has met the conditions for dynamic debugging. The subsequent steps will include dynamic debugging and trial operation.
Line 7 Phase I to Fill a Gap in Zhengzhou’s Metro Network
Upon completion, Line 7 Phase I will fill the gap in the southwest area of Zhengzhou that lacks metro service. It will provide a more convenient choice for long-distance travel within the city and accommodate high-capacity passenger flow. This will play a positive role in expanding the radiation range of the main urban area of Zhengzhou and promoting the integration of urban and rural development.
Other Construction Projects Also Making Progress
Meanwhile, the northeast section of the Phase I project of Line 6 and the Phase I project of Line 8 are proceeding smoothly with unloading test runs. The Zhengzhou Metro Group is working tirelessly to accelerate the construction progress, aiming to open and operate the three under-construction lines as soon as possible.
Conclusion
The successful heat slide test of the Phase I project of Zhengzhou Metro Line 7 is a significant milestone for the city’s metro network expansion. It is a testament to the progress and dedication of the construction team and the growing importance of public transportation in urban development. As the city continues to grow, the completion of Line 7 Phase I will undoubtedly contribute to a more convenient, efficient, and sustainable urban transportation system.
