Currently maps in different views behave somewhat random manner when user clicks/taps the map. Some views show a popup with location information, some don't.
Location information - address and ticket zone - is probably useful in all views.
In desktop view, the popup also sets start, end and middle points for an itinerary search in entry page and in itinerary page. This is intentional design. However, origin and destination selection are available also in stop and route page. That is somewhat confusing and those selections do unexpected things.
Design and implement consistent popup menu setup and content for all views.
