Cross-sea subway begins trial runs in Dalian

Dalian Metro Line 5, the first cross-sea subway line in Northeast China, started a trial run on Wednesday in Dalian, Liaoning province.

With a total length of 24.48 kilometers and 18 stops, the north-south line, which is the sixth metro line of the port city, connects two of its major urban functional areas.

The subway line is underground all the way and crosses 2,310 meters of sea. A number of independent technologies and equipment have been adopted in the construction to meet the engineering challenges.

During the half-month trial, the subway company expects to collect suggestions for corresponding optimization and upgrading about the following construction and upcoming operation.
