Summer
Listen to Anna, then exit the compartment and go right first. Move past the tank car and find yourself on a platform with a car. On the table on the right is the only document of the chapter - Tetashnik's note.
Next, go to the table with everyone, listen to the stories and find out Anya's terrible secret. Follow the Miller and chat with him, then go back to everyone. Listen to the song or go straight to the head car, where you interact with the map to start the quest.
