The Qinghai-Tibet Railway has passed safety and environmental tests and brought economic prosperity to formerly inaccessible Tibetan areas.

Around 550 kilometers of the 1,956-km railway on the world's highest plateau is laid on permafrost. Linking Xining, capital of Qinghai province, and Lhasa, capital of the Tibet autonomous region, it has transported more than 52 million people and 240 million metric tons of goods since it became fully operational in July 2006.

In 2011, Tibet received 8.6 million tourists, up from 1.8 million visitors in 2005. Tibet's tourism industry generated 9.7 billion yuan ($1.53 billion) in revenue in 2011, five times the amount in 2005.
