Innovations accelerate railway building safety

Chinese railway builders are intensifying innovations in a bid to realize a leapfrog upgrade in the intelligent construction of railways and enhance work safety.

In Gansu province in Northwest China, State constructors helping to build the Tianshui-Longnan Railway have developed 10 process methods, raising construction efficiency by some 20 percent.

On June 13, the 16.27-kilometer Xujiaping Tunnel on the railway, which links the two prefecture-level cities of Tianshui and Longnan in Gansu, was fully dug through by builders from China Railway No 4 Engineering Group Co Ltd.
