CHONGQING (CQNEWS) -- Since entering the summer vacation, hot weather has frequently appeared. Although there are many places where people can go to avoid summer heat, some special posts can only be carried out in the sun. In the railway system, there are a group of "bridge guardians" working in the sun. During the summer, they step on the steel girder bridge whose temperature is over 50 °C every day to inspect and maintain the railway for the safety of railway transportation. Recently, the reporter approached the group of guardians under the scorching sun and experienced the feelings how hard they work in the sun.

Compared with the adjacent old Chaoyang Bridge, the Steel Beam Bridge was not built for a long time, but in the railway system, this bridge is the "throat" of the railway, and it is still in service as the oldest bridge on Xiangyang-Chongqing Railway. It also has a feature, that is, the only railway bridge with full wooden railroad ties in the main urban areas of Chongqing. The wooden railroad ties naturally increase the difficulty of maintenance, especially in winter and summer.

Manually clean the rails.
