In the early morning of January 26, the transformation and distribution maintenance workers in the Rongjiang transformation and distribution operation and maintenance work area of the Guiyang power supply section of China Railway Chengdu Bureau Group Co., Ltd. seized the 3-hour "skylight period" to inspect the AT located in the Yanshan Tunnel of the Guizhou-Guangzhou high-speed railway. The equipment carries out inspection and maintenance operations to improve the quality of power supply equipment for high-speed rail lines during the Spring Festival travel period and ensure transportation safety.
Because the transformation and distribution maintenance workers in this work area spend most of their time working in the tunnels located on the high-speed rail lines, they are also called "tunnel warriors".
The picture shows the transformation and distribution maintenance worker opening the door of the AT station of Yanshan Tunnel.
