en.Wedoany.com Reported - Recently, the Houyue Railway officially launched intensive maintenance operations, conducting comprehensive repairs and upkeep on the line to strengthen equipment and facilities, ensuring safe and smooth transportation for the upcoming summer energy supply.

The Houyue Railway, running from Houma in Shanxi to Yueshan in Henan, is an important southern corridor for "Shanxi coal outward transport." As a major energy transportation artery connecting Shanxi and Henan, the line handles an annual freight volume exceeding 100 million tons, providing strong support for energy supply security and regional economic development.

This intensive maintenance focuses on replacing rail sleepers in sections and mechanized ballast bed cleaning, scheduled from May 28 to June 18. During the maintenance period, China Railway Taiyuan Group arranges a 180-minute "window" without train operations daily, planning to complete 29.753 kilometers of mechanized ballast bed cleaning, replace 13,931 sleepers, and renew ballast for 24 sets of switches. Large machinery will also be used for tamping, grinding, and replacing switch rail components in groups, alongside inspections and repairs of communication cables, signals, and power supply catenary systems.

As the main construction unit, the Houma North Track Maintenance Depot has introduced new flash butt welding technology for switches for the first time during the Houyue Railway intensive maintenance. This technology enables welding with automatic temperature and pressure control and real-time parameter monitoring throughout the process, eliminating human errors and providing technical support for improving efficiency and quality in intensive maintenance. Wang Qingao, business manager of the Track Maintenance Department at Houma North Track Maintenance Depot, explained that flash butt welding offers high strength and minimal deformation, effectively enhancing the stability and load-bearing capacity of welded rail joints. This not only improves the smoothness of train passage but also significantly reduces wheel-rail wear. The plan is to perform flash welding on 18 sets of switches.
