Chinese railway operators have taken timely measures to bolster the safety of bridges and tunnels on high-speed railway lines amid snowy weather. Upon receiving a snowfall warning, the Taiyuan High-speed Railway Engineering Section in Shanxi province immediately initiated an emergency response, calling on each workshop and working area to intensify inspections in advance to monitor equipment status on rail bridges and tunnels. During snowfall, operators utilize off-peak hours to conduct foot patrols on bridges and in tunnels to promptly clear ice and snow, while strictly enforcing on-site safety protection.
