Wikipedia is not a travel guide
Wikivoyage has a travel guide for Rail travel.
Articles on stations could include information about their facilities and amenities, but providing a listing of every ordinary or mundane facility may be considered excessive. It is not notable to tell us whether a station has toilets (unless there has been notable coverage specifically about this presence/absence), but it may be to tell us that the station had/s Motorail facilities. If the station has a shopping centre attached, tell us this; there is no need to specify the shops. Information useful to travelers is very welcome at Wikivoyage.
當然正如佢提到,個站幾時加咗廁所就值得睇。其他地方例如 Wikivoyage 會適合跟住晒每個站有咩鋪頭多啲。
