Employees from the Yuanping track division of China Railway Taiyuan Group Co conduct maintenance and inspection work on railway line equipment within their jurisdiction. The work, part of the local railway operator's spring inspection and maintenance campaign, aims to eliminate potential safety defects, bolster equipment performance, and secure the safe and stable operation of passenger and freight trains on the arteries linking Shanxi province with the national railway network, which also forms a key part of China's energy transmission channel.
