On August 28, 2024, Aigre successfully completed the first ultra-high 175 rail replacement operation of the Beijing-Guangzhou high-speed railway.

The Beijing-Guangzhou railway is China's main trunk line with the most provincial capital cities connected and the most interconnections with other lines. Every maintenance and upgrade of the railway arouses the concern of hundreds of millions of people. Aigre, with its outstanding professional ability and forward-looking vision, took on the heavy responsibility of preparing for the track replacement operation. From precise measurement and planning to efficient construction execution, Aigre paid attention to every detail to ensure that the track replacement operation was completed safely and accurately under normal operation conditions.

The successful completion of the track replacement operation is the beginning of Aigre's contribution to the railway transportation industry. Aigre looks forward to the successful completion of more high-speed railway projects!
