I think it is a good idea indeed. The Wiki page of railway=station
says the following:
railway=station should be tagged as a node, placed at the centre of the station from the passengers’ point of view (i.e. near platforms), or as an area covering the whole station.
And the Wiki page of public_transport=station
says:
A station will normally have some, but not all of the following attributes:
- Have a physical presence consisting of a building or other structure […]
- Have a number of platforms and stop positions […]
- […]
- Have amenities for waiting passengers including shops, vending machines and information services and possibly car parking […]
- […]
The station itself is mapped as an area, usually covering the outline described above […]
So railway=station
should cover the whole station (from a railway infrastructure perspective), but public_transport=station
should only cover the public area of the railway operating site.
I agree, but train=yes
applied on the same area as public_transport=station
is could indicate that it’s a railway public transport station.
