Innovative ideas boost high-speed travel experience

Innovative designs have enabled the introduction of high-speed railways into mountainous regions and enhanced passengers' travel experiences.

The Xi'an-Chengdu high-speed railway, which opened on Wednesday, is the first high-speed line traversing the Qinling Mountains in Shaanxi province.

As the dividing line between China's north and south regions, the Qinling Mountains have complex geological conditions and a diverse ecological environment.
