Many foreign travelers who plan to travel to Tibet by train may be confused by this question that why they can’t book Tibet train ticket on internet by themselves.
The major reason is that the Qinghai-Tibet Railway is an extremely popular tourist railroad in China. Each day, thousands of travelers travel to Tibet via this railway.
Another reason is that because most train tickets, sleeper tickets in particular, are reserved by travel agencies. Generally, the travel agency who can guarantee the train tickets, attracts more customers.
