Track laying for a high-speed railway linking Beijing and Xiong'an New Area in neighboring Hebei province was completed on Monday, marking a countdown to the full operation of the line, according to the local railway operator.

Scheduled for operation by the end of this year, the Beijing-Xiong'an high-speed intercity railway will shorten travel time between the two places from the current two hours to one hour, said China Railway Beijing Group.

The railway, which stops in downtown Beijing, Beijing Daxing International Airport and Xiong'an, will improve the high-speed railway network in the Beijing-Tianjin-Hebei region, the company said, adding that it will play a significant role in facilitating the coordinated development of the region and supporting the construction of the Xiong'an New Area.

Stretching more than 92 kilometers, the new intercity railway line consists of two sections. Apart from the link between downtown Beijing and the new airport, which opened last year, the section linking the airport with Xiong'an will see trains operate at a maximum of 350 kilometers per hour when put into service, said Deng Yinjie, deputy director of the company's project management department.

To make the line a world-class high-speed railway offering fast, smooth and comfortable service, railway experts relied on the construction experience of the country's previous high-speed railways and carried out technical research on the rail track structure.

"It's a new challenge beyond the current track smoothness across the world," said Gao Zengzeng, a track expert from the China Railway Design Corporation, adding that with precise soldering of the track in place, the high-speed trains are able to run more smoothly and steadily.

China announced plans to establish the Xiong'an New Area in April 2017 to take over functions nonessential to Beijing's role as the national capital. Xiong'an's city proper will be a new home for Beijing's colleges, hospitals, business headquarters and financial and public institutions.

Later in 2018, the country kicked off construction of the Beijing-Xiong'an intercity railway, with a total of 33.5 billion yuan ($4.83 billion) invested in the project.
