Experts warn of subsidence threat along new railway

Extracting underground water poses danger to line's stability

BEIJING - Railway experts have called on local governments along the Beijing-Shanghai high-speed rail line to stop jeopardizing the landmark project by drawing underground water.

Subsidence of the foundation of the Beijing-Shanghai high-speed railway must be kept within 5 millimeters in 100 years, if trains run at 380 km/h on the 1,318-km-long line.
