Furthermore, some stations have been accepted in my area (or have been added by Niantic as automatic PokeStops).

The bus stops/stations may have been added as part of this experiment.

Testing New Wayspots in Pokémon GO

Hello Wayfinders, You may have noticed that there are some newly added Wayspots in Pokémon GO in selected areas of France, Italy, and Spain. These Wayspots have been added to the map as part of an experiment designed to enhance gameplay and increase accessibility in areas with low Wayspot density. Curious about this experiment? We’re embarking on an exciting test to measure the impact of adding Niantic-generated Wayspots in safe, pedestrian-friendly locations like street corners and bus stops…

but it doesn’t make others eligible
