First of all I have to apologize about my poor English (I'm from Italy) but I hope you can understand what I'm trying to write.
I'm starting to think about a Moscow - Chita - Ulan Bator railway trip next year.
I'll be travelling solo (I have some experience after 8 years) and I do not speak a single word in Russian (but I can read cyrillic).
I'm on tight budget and my main interest is photography - I travel with some fairly expensive cameras and lenses.
So here are my questions - I'm afraid you already answered some hundred times!
1) when? I'd like to avoid July and August, so is it better late spring or early autumn?
2) what? which are the stops I cannot miss on the way from Moscow to Chita?
3) how? do I have to reserve all train tickets in advance or is it possible to buy them at the moment?
4) how (2)? second or third class? I'm thinking about 2nd for overnight legs and 3rd for shorter ones.
I think this is enough for the moment; thanks a lot for your answers!
