Only half an hour left before the end of maintenance time. At 10 a.m., the sun was getting hotter and hotter and the heat was coming in waves. The overhead contact lines workers were stepping up to complete the final process.

Today, at the peak of the summer rush, there is an endless stream of trains coming and going from south to north. These overhead contact lines workers stick to their posts under the hot sun, guarding the safety of millions of passengers. Thank you, railway Spider-men!
