Since its commencement on June 29 th , 2001, the Golmud-Lhasa Section (G-L Section) of the Qinghai-Tibet railway has been advancing safely and smoothly, with high construction quality. Up to now, the main structures along the whole section are nearly completed, experimental projects in the post-station section are almost concluded (except signal works), tracks of 743 km have been laid. In 2005, the whole project entered its decisive stage. The goal of this year is: totally complete the sub-track works, nearly complete post-station works, completely link up the whole section. During the construction, three major obstacles must be removed, i.e., permafrost soil, deficient oxygen content in arctic alpine regions, and the fragile ecological environment. Up to now, remarkable achievement has been made in struggling with the three problems, and precious experience of constructing railway on permafrost plateau has been acquired. All the roadbeds, culverts and tunnels are of stable and reliable quality so far.
