China's Tibet Autonomous Region is expected to start running bullet trains before July 1, marking the opening of high-speed train services in all Chinese mainland provincial-level regions, the country's railway operator said Saturday. A 435-km railway link to the regional capital of Lhasa will run Fuxing trains powered by both internal-combustion and electricity, Lu Dongfu, board chairman of China State Railway Group Co., Ltd. and a deputy to the National People's Congress, told Xinhua. Construction started in 2014 on the railway connecting Lhasa with Nyingchi in eastern Tibet. It is the first electrified railroad in Tibet and is slated to begin operations in June 2021. The track-laying work was completed by the end of 2020.
