BEIJING: To overcome possible altitude sickness, oxygen will  be supplied to passengers travelling on the Qinghai-Tibet railway, the world’s highest, when passenger services commence in July, state media said.
 
“Oxygen will be supplied by using a system like central air-conditioning on trains,” deputy manager of the Qinghai-Tibet Railways Company, Ma Baocheng said.
 
Oxygen masks will also be installed under seats, which can be used if passengers feel sick.
 
Also, each train will have a doctor and a nurse for emergencies.
 
The 1,956-kilometre-long Qinghai-Tibet Railway links Xining, capital of the Chinese province of Qinghai, to Lhasa, capital of Tibet Autonomous Region.
 
The trial operation will be launched on July 1.
 
The Qinghai-Tibet Railway is by far the longest plateau railway with the highest altitude in the world.
