Shanghai-Kunming high-speed railway tunnel problems fixed

China Railway Corp has fixed problems found in tunnels along the Shanghai-Kunming high-speed railway to ensure safe and interruption-free operations, the company said in a statement on Thursday.

Some tunnels in the Guizhou section of the Shanghai-Kunming high-speed line developed cracks and leaks as a result of heavy rains over the summer, signaling potential safety hazards.

"The railway department has always prioritized safety for the railway and passengers, and no safety hazard is acceptable. The railway department will never ignore any construction or engineer ing quality problems. They must be fully rectified," the company said. "The department will identify the responsible parties, which will be punished in accordance with the law and their contracts." Thepaper.cn reported on Tuesday that serious problems were discovered in some tunnels along the Shanghai-Kunming high-speed railway, including substandard construction materials that posed safety risks.
