My friend and I are planning to go to Tibet in late April next year. We will be in Tibet for 7 days.
We will take the Qinghai-Tibet railway both ways between Xining and Lhasa. There is no problem on the way to Lhasa as far as we get the tickets (soft sleepers). However, on our way back from Lhasa, we will have to take the 9:00 am train because of our flight from Xining.
1) No one mentions so far whether the trains run on time or not. Is it usual that they are always delay half an hour or so, or over one hour? We have 3-hour leeway between the official train arrival time and airplane departure.
2) The 9:00 am train runs every 2 days according to the train time table. How can I figure out what days the train actually runs?
