en.Wedoany.com Reported - Recently, with the precise placement of the final new switch, the first switch replacement blockade construction at Erlian Station on the Ji'er Railway was successfully completed.
The Ji'er Railway handles heavy international intermodal transport tasks, and Erlian Station is China's largest land port open to Mongolia, characterized by high train density and frequent shunting operations. Some existing switches in the station have exceeded their service life, and the safety risks posed by aging equipment are becoming increasingly prominent, necessitating urgent remediation.
During construction, given the limited working space at Erlian Station, the China Railway Sixth Group's operating line renovation project team implemented refined management throughout the process. The technical team planned ahead, developed a specialized construction plan and safety control measures in accordance with operating line construction specifications, detailed the construction procedures, clarified job responsibilities, and conducted comprehensive safety and technical briefings for all personnel. During the process, the site strictly adhered to the operating line blockade construction management system, with full closed-off safety protection and designated personnel monitoring work areas in segments. Workers followed standardized construction techniques, orderly carrying out key procedures such as removing old switches, clearing the base, laying new switches, positioning, tamping, and fine adjustment. All work groups coordinated closely, strictly controlling construction precision and operational safety, ultimately completing the task within a 240-minute "window" period.
After the completion of this switch replacement, equipment defects caused by long-term service of existing switches will be eliminated, effectively improving the track passage conditions for locomotive entry and exit from the depot and shunting maneuvers, enhancing the stability and safety bearing capacity of the Ji'er Railway operating line equipment, and further ensuring the orderly operation of railway transport at the border port.
