I know there is very similar question, however it was in 2011 and many things have changed since then. Now is 2016.
I'm interested in public transportation overland (buses, trains), least - oversea, but no flights at all. I feel fairly ok with travelling through Iran. This month sanctions lift (in regard to anti-nuclear policy) shows the relations of Iran with "West" are getting better and the country is getting more hospitable and somehow open for other views. Also the number of hostels are increasing which is another good indicator. I know there was some pretty decent railway connection from Ankara to Tehran, however with latest hostilities on border with Syria and some local Kurd uprisings on the east it got suspended and foreign offices discourage to go in southern and eastern Turkey, near the border. So this is "problem A" - is there still some fairly safe route to travel from Turkey to Iran overland?
Another problem is Pakistan - which is problem B. Pakistan for me is simplest route to India from Tehran (I don't even mention Afghanistan). Do you know of any fairly safe land route for transit thru Pakistan? I've read about not so uncommon foreigner abductions (like FATA regions and Baluchistan). Are there some regions strictly under government control with minimized partisan influence (which can be avoided with proper rules and some basic knowledge about region)? Or perhaps some public sea transportation from Iran to India is available?
Also I'd like to avoid getting thru Russia.
To add some context to this complex matter - I'm male in early 30's, white, born in central-eastern Europe, with good English, some French and good manners.
