Question: train tickets
I am considering a train ride in spring 2019, following the Silkroad.
There is no problem to organize the first part, Beijing to Tashkent. A Dutch travel-agent sells me the tickets, organizes the visa and the stop-overs.
My intention is to continue my trip from Tashkent to Teheran and from Teheran to Istanboel. By train.
Can you help me with tickets, stop-overs and visa?
