brief introduction

Lanzhou-Xinjiang Railway passes through "Baili Wind Zone" and "Sanli Wind Mouth", so the construction and transportation are extremely difficult. Earth and stone works of subgrade110.83 million cubic meters were completed in the whole line; There are 33 tunnels with a total extension of11.8km; Bridge 1 1 17, with a total length of more than 30 kilometers; Main track laying 1953 km.

Hekou Yellow River Bridge, 35km away from Lanzhou West Railway Station, is the first Yellow River Bridge designed and built by China. Bridges and tunnels in Wushaoling area are relatively concentrated, and there are Tianshan tunnels between Hougou and Dabancheng, as well as subgrade projects across windy areas, which are all key projects in the construction of Lanxin Line.
