“The first electrified railway in Tibet was inaugurated on June 25, with ceremonies in Lhasa to mark the start of operations on the Lhasa – Nyingchisection of the Sichuan - Tibet railway.
”Diverging at Xierong from the Lhasa – Xigatse line opened in August 2014, the new line runs for 404·8 km to Nyingchi, also known as Linzhi, around 15 km from the border between the Tibet Autonomous Region and India.”
“The line has been laid out for 160 km/h operation, with trains covering the 435·5 km between Lhasa and Nyingchi in 3 h 30 min. China Railways is initially providing three D category trains in each direction, operated by CR200JS-G electro-diesel trainsets. The nominal freight capacity of the route is put at 10 million tonnes per year.”
