Hi,
I will be taking overnight bus from beijing to Erlian, then crossing the border to take train from Zamyn Uud. Any possibility of the train ticket to be sold out from Zamyn Uud to UB? I guess I cannot pre-book this ticket from anywhere and also do not wish to stay overnight in Zamyn Uud.
Anybody knows about the express train schedule from Zamyn Uud to UB?
