Test runs on an intercity high-speed railway line linking Beijing and Xiong'an New Area in Hebei province entered their final stage on Tuesday, China Railway Beijing Group said.
The line is expected to open at the end of this month.
Initially, trains will take about 50 minutes to travel from Beijing West Railway Station in the capital's Fengtai district to Xiong'an Railway Station in Xiongxian county, it said.
"In the future, the time can be cut to about 36 minutes after further upgrading of an old section of the line," Li Zheng, a Xiong'an Intercity Railway director, told China Central Television.
The 93-kilometer line runs southwest from Beijing and has two parts. The first section, from Beijing West to Liying Railway Station in the capital's Daxing district, is part of the existing Beijing-Kowloon Railway, which extends to Hong Kong. The second section, from Liying to Xiong'an, is newly built.
