@piggo and like, the most egregious usage of „Główny" must go to Wałbrzych and Kłodzko where you have Wałbrzych Główny and Kłodzko Główne, but also Wałbrzych Miasto and Kłodzko Miasto, and in case of Wałbrzych, also Wałbrzych Centrum, all three of which are more important passenger-wise than "main” stations
