The world's highest railroad
To date, tickets for the six lines to Tibet -- including from Beijing to Lhasa -- have been booked by travel agencies, according to railway sources.
The world's highest and longest plateau railroad will be sealed like an aircraft to protect passengers from the effects of high altitude.
Passenger trains will depart in the morning and arrive in the evening, giving travellers enough time to enjoy the plateau's natural beauty.
