We're working on live public transport schedules as the first step to public transport routing. Here is the helper web app that shows currently supported GTFS feeds in different countries and cities and helps to match bus/tram/train stops from OpenStreetMap.org with stops from GTFS: https://gtfs-osm-matcher.organicmaps.app/
If you are interested in public transport schedules in your city, please let us know about feeds for your place/country, and help by adding/editing stops in OpenStreetMap.org

@organicmaps It seems that for the Netherlands, you need to also use a different reference field into account as well: ref:IFOPT

See for example https://gtfs-osm-matcher.organicmaps.app/#/match-report/netherlands/selection/no-match/3479640 — the stop is there, with:

ref:IFOPT="NL:Q:41321660"

This matches the Gtfs stop Code.

Similarly with https://gtfs-osm-matcher.organicmaps.app/#/match-report/netherlands/selection/no-match/3479647, https://gtfs-osm-matcher.organicmaps.app/#/match-report/netherlands/selection/no-match/3828602, and quite a few others.
