The Qinghai-Tibet Railway, the world's highest railway and a vital link to remote Tibet, has not been affected by a 5.2-magnitude earthquake striking nearby on Monday morning, its operator said on Tuesday.
Though people in some stations along the line said they felt obvious tremors, the railway is operating normally, said sources with the Qinghai-Tibet Railway Company.
The earthquake, with a depth of 10 km, struck Qilian County of Haibei Tibetan Autonomous Prefecture in Qinghai at 5:02 a.m. on Monday, according to the China Earthquake Networks Center (CENC).
No casualties have been reported. Fourteen households sustained cracks in their walls, with 46 residents relocated, the county government said.
The 1,956-km Qinghai-Tibet Railway, which began service in July 2006, is the world's highest and longest plateau railroad and also the first connecting Tibet Autonomous Region with other parts of China.
