splitting underground platforms lengthwise to accommodate stairs/escalators/elevators
I'm not sure it makes sense to tag the stations themselves as "level=-2". I would consider the entire facility (the concourse level, platform level, elevators, etc. to be the station. It would make sense for the individual elements inside the station to get a level tag though.
I see what you're saying. I would consider the platform level to be the relevant level to assign to the station, the rest being just indoor pedestrian circulation. Either way, I guess it's unclear whether the level tag belongs on the station node in the first place.
I want to think through to alternate ways of mapping stations. Station polygons fulfill the same role as station nodes, and they're drawn as a convex hull around the stops and platforms (and switches if present). If I were to trace the station polygons here, should I assign them a level tag? If so, what?
The most straightforward answer to me would be to have one polygon for each station, and to assign it the same level as the railway infrastructure it surrounds. I'd like to hear your thoughts.
