Amidst the harsh winter conditions of Northwestern China’s Kunlun Mountains, a dedicated team of railway mechanics from the Wangkun Line maintenance workshop is undertaking critical patrols and maintenance operations to ensure seamless rail transportation during China’s peak Spring Festival travel period. These technicians, operating under China Railway Qinghai-Xizang Group Co., Ltd., have intensified their surveillance of vital railway segments along the Qinghai-Xizang Railway route, working in sub-zero temperatures to guarantee passenger safety and operational continuity.
The maintenance crew, based in Golmud, Qinghai Province, faces extraordinary challenges due to the region’s extreme altitude and severe weather patterns. Their work involves meticulous inspection of tracks, monitoring structural integrity, and performing essential repairs along one of China’s most crucial high-altitude rail corridors. The team’s efforts become particularly significant during the Chunyun period—the world’s largest annual human migration—when millions travel across China for family reunions during the Lunar New Year celebrations.
Photographic documentation from February 6, 2026, captures these technicians executing precision maintenance work on the rail infrastructure, demonstrating their commitment to maintaining China’s extensive railway network. Their behind-the-scenes efforts represent an essential component of the national transportation system’s reliability, especially in remote regions where environmental conditions present unique operational difficulties. The continuous monitoring and maintenance activities ensure that the Qinghai-Xizang Railway remains fully operational throughout the holiday season, facilitating safe passage for travelers undertaking their seasonal journeys.
