The birth of long tracks for high speed railway (6)

The Nanchang-Hangzhou section of Hu-Kun (Shanghai-Kunming) high speed railway will start operation by the end of this year. No visible joints can be found along the 350-kilometer track, which is set to serve the highest speed of 582 kilometers per hour. Trains will run on the track smoothly with no noisy sound.

Xiangtang welding workshop in Nanchang is one of the 11 welding workshops for railway tracks in China. Welding work of 1,254 kilometers’ track of the Hu-kun high speed rail line is done by this workshop.

Five 100-meter-long tracks will be firstly joined to form a 500-meter-long track through welding, and then workers will transport these longer tracks to the construction site and weld them to a seamless track lying along the rail line.
