Unable to answer "Is this place wheelchair accessible?" for https://osm.org/node/1123933063 via StreetComplete 56.0:

This entrance is not wheelchair accessible. Actually none of the entrances are. However, only exception: Across the street there is an elevator to the ticket level and from there are other ones to the platform.
However, the first elevator is currently out of service and I am not sure how long that state will persist.
