I arrived at the train station in the morning. Clear. Comfortable. But at night..... There are "suspicious people" walking around, stoned. And next to it is a "red light street" with "girls" in the windows.
The station itself is excellent, everything is modern, ticket purchase and navigation are simple. There is a place to eat and wait for the train. Around the station is straight Harlem and Kupchino in one bottle)) Muddy types, red light street and all that stuff. Be careful there ;)
