Stretching across remote, breathtaking terrain, the Lhasa-Nyingchi Railway stands as a marvel of modern engineering. Two of its structures—the record-breaking Zangmu Yarlung Zangbo Railway Bridge and the seismic-prone Bayu Tunnel—rank among the world’s most challenging railway assets.
Behind the scenes is the Jiacha maintenance team: 13 young bridge and tunnel engineers, all born after 1990, who hail from nine provinces and autonomous regions across the Chinese mainland. Together, they defy extreme conditions to keep these giants in top shape.
Every mission demands climbing dizzying heights—up to 40 stories above the valley floor—and navigating four-hour drives along narrow mountain roads. With each check, their goal is clear: to ensure the Fuxing bullet train can cross the Zangmu Bridge in a mere 12 seconds, safely and smoothly.
