Non-technical users have difficulties, when opening a detail window with a mobile phone, in understanding how to close it and return to the map. The button "Back to map" seems to be not sufficient. I would add in the top right of the detail window a "X" near the name of the station, which is more visible and clear by the user. In italian, I would change "Mappa" in "Torna alla mappa". In German, I would change "Karte" in "Zur Karte".
