The beautiful architecture of the station in a pseudo-historical style, trains travel on time, I personally did not notice any disadvantages. From here you can take the train to Baku.
It is impossible to buy tickets at your own price! Sellers say that there are no tickets, but through friends you can buy tickets without problems. And when we got on the train, there were plenty of empty seats.
But that was a few years ago. I don't know, maybe the situation has changed?-;)
And so everything is clean, neat.
