The Taijiao Passenger Dedicated Line (Taijiao Intercity Railway) is a significant transportation infrastructure project planned by the provinces of Shanxi and Henan during the “Twelfth Five-Year Plan.” It is an important component of the Zhengzhou to Taiyuan Railway (Zheng-Tai High-Speed Railway). The Taijiao Passenger Dedicated Line has a total length of 362.095 kilometers, with 328.178 kilometers within Shanxi Province and 33.917 kilometers within Henan Province. The designed operating speed is 250 km/h.

In 2019, our company undertook the task of supplying approximately 10 kilometers of sound barriers for this project. The main construction distribution points are along the Taijiao Railway in Changzhi City, Xiangyuan County, and Wuxiang County in Shanxi Province.
