Team tackles ice in 20-km railway tunnel

For nearly a decade, a team of technicians has spent the winter months shoveling and removing ice from a railway tunnel in Shanxi province to safeguard passengers' trips.

The technicians are in charge of patrolling and maintaining all the bridges, tunnels, culverts and roadbeds along the Lyuliang section of the Taiyuan-Zhongwei-Yinchuan railway, which stretches 165 kilometers across mountainous terrain in northern China.

During the grueling winter months, when temperatures in the 20-km tunnel can plummet to as low as -19 C, the technicians are responsible for clearing snow and ice from the railway tracks.
