станция Рясна

This is not a train station, it is a train stop like what you used to find in the US out in the middle of nowhere. If there is someone standing there the train will stop. As you can see in the Street View there is a "Greek Catholic" (a.k.a. Ukrainian Catholic) church on one side of the tracks. That is the side you stand on if you are going away from Lviv, the other side towards. "станція" is translated stop rather than station in this context, like a bus stop.
