Guard brigades ensure Qinghai-Xizang Railway security

The 54-man team's usual task is to stand guard and eliminate any potential safety hazards along 900 meters of the bridge section to ensure the railway operates normally, he added.

Xu Sanren, a squad member, said he and his partners take turns standing guard for two-hour shifts. When someone approaches the railway, they report it to the sentry post via walkie-talkie, and then the squad sends personnel to investigate and resolve the issue.

"Occasionally, there are drunken individuals who come near the railway at night," said Xu.

After graduating from university, Xu decided to join the military because he thought it was cool. When he came to Xizang, it was not as challenging as he had imagined.
