The trains arrived on schedule. But I did not have enough of a cashier from whom I could buy a ticket and specify the platform I needed. There is no such problem when going to the airport or to the final destination station, because they will be reflected on the scoreboard, but the intermediate ones are not. Maybe it just became a problem for me. Fortunately, I was prompted in the cafe at the train station to the right platform. I bought the ticket at the vending machine. At the same time, it should be borne in mind that the Russian language is not included in the choice of languages, it may not accept coins, or it may not accept paper money, but only cards. Perhaps the card is the most convenient payment method, because you may not receive the change.
