Ideal Location

As places go there are a few cities I want to go to; Moscow, Tokyo and Vienna. I love wandering around with a camera in my hand, it is I guess my idea of a perfect day with loads of stops for good strong black coffee. The trip that I really want to make is the Trans siberian Railway, stoping off a few places on the way going from Moscow to Beijing. The bonus is that there are a couple of routes so I could take a different route on the way back.
