A few months ago, a user added a large bunch of elements inside the station (e.g. https://www.openstreetmap.org/way/1199403262) and that created the mess to which you are probably referring: most objects are far from their real location and not connected, and are in fact close to impossible to reconcile with the existing geometries.

Can you please clarify what you meant with "needs to be checked physically"?  Are you willing to help?
