Sorry, yes I meant samePlaceAs… not our famous owl:sameAs :)

Exactly! The point is that it’s more easy to get the geometry for the station, but not always the case for inner entities like in the above shop example. 
That’s  why we can use the samePlaceAs for this “kind” of relations.

Instead, I would say 'ex:fireIncident-56a38 tookPlaceAt <https://g.co/kg/m/02s5hd <https://g.co/kg/m/02s5hd>>' or from an event perspective 'ex:fireIncident-56a38 involved < <https://g.co/kg/m/02s5hd>https://g.co/kg/m/02s5hd <https://g.co/kg/m/02s5hd>>' or ''ex:fireIncident-56a38 covered <https://g.co/kg/m/02s5hd <https://g.co/kg/m/02s5hd>>' (if the space is the key issue here), or  any other form of modeling the relation between the incidents and places. This seems way more useful to me than saying that the fire incident is the same place as the house; after all I want to say that the fire happened there not that they are the same.
