What do you think about adding another class to the train stations to
distinct them from subway stations? I suggest to add
railway=subway_station for the latter and keep railway=station for
train stations. It is mostly deductable from the railway tracks (or
route relations if any) if it is a train station or a subway station,
but this requires IMHO unnecessary postprocessing. Beeing explicit
would be the easier approach. Are there any problems with doing so?

IMHO this would not cause many problems in the transition phase, at
the worst a subway station might be interpreted as a train station if
the application is not clever enough to look at the tracks, but it
would facilitate use of the data for the simpler applications once we
reviewed all stations (currently 66 724).
