Tests on Zhangjiakou rail link in 2019

An automated high-speed railway line linking Beijing and Zhangjiakou, host cities of the 2022 Winter Olympics, will be tested in 2019, said its manufacturer on Thursday.

"The fully automated train will be built using environment friendly materials," said Wang Run, a deputy to the 13th National People's Congress and chairman of CRRC Changchun Railway Vehicles Co.

The 174-kilometer intercity railroad is a high-speed rail line, with a designed speed up to 350 km/h. Construction work on the line began in April 2016 and is expected to be completed by the end of 2019. There are 10 stations along the line, under the government plan.
