Ideally would like to take train on 16 September from Xining to Lhasa. Looking at ctrip gives a selection of available trains. However China DIY show 'no availability at all, email us'. They now say that due to current selling conditions there are only 3 trains with hard sleepers that have availability. As tickets haven't gone of sale yet, I am very confused! Is China DIY giving me better advice? Do they have more live access to ticketing? Also when will I know if the booking is successful? I need to book connecting flights. Any help appreciated!
