Stop and platform for a subway station?


What is the convention for stops and platforms for subways?

The reason I ask is that I see that the subway line Linea 8 in Madrid Spain has an associated platform “Nuevos Ministerios”, but no associated stop. Would it be appropriate for me to associate that location as a stop for Linea 8? What are the considerations for doing this?

I would think that if a platform is associated with a subway line, then there should be a stop there also. To me, a platform is more like a building and a stop, a point on a rail line.


I got some enlightenment from

but I’m not sure I could keep out of trouble with the knowledge I gained by reading that. Rereading may help. A good annotated example would also be helpful. If anyone could direct me to such a thing, I would be grateful.
