With a total length of 6,984 meters, the Huajiashan Tunnel is the longest tunnel on the Guangxi coastal high-speed rail line. In order to protect the safety of the tunnel, the Qinzhou Public Works Section of the Guangxi Coastal Railway Company has set up high-speed rail lines and line inspection teams to escort passing trains.
During the Spring Festival, the high-speed rail line inspection team increased the frequency of inspection, and every time the line ran during the "skylight period", it was often seen that the staff relied on headlights to walk through at night, timely check various hidden dangers that may occur in the tunnel, and ensure the safe operation of more than 80 trains passing through the tunnel every day.
