I don’t know why, but I don’t have very good emotions about Russian Railways in Sochi. This may be due to the large distance between checkpoints and ticket offices. Maybe because every time the trains did not run according to schedule. Or the reason was that I could not get tickets at the station. I always had to buy them on trains.
This railway station in Russia really surprised me it’s look like mini airport ,very highly class railway station only one minus point when you book taxi you have to come outside,because inside area taxis are not allowed, overall wonderful experience everything was also explained in English.
