Beijing, July 28 (DPA) Cracks in concrete sleepers and thawing of permafrost threaten to undermine the rails of China’s controversial new line to Tibet, state media said Friday.
‘Frozen ground used as the foundation for the railway is sinking and cracking along a few sections, and this makes some parts of the railway unstable,’ railway ministry spokesman Wang Yongping told the Beijing News.
‘Concrete on some railway structures and bridges is cracking and poses a hidden danger to the quality of the railway,’ Wang added.
Other teething problems along the new line include yaks wandering onto the railway and sand covering some sections, Wang said.
