Upon closer inspection, this appears to be one of two inadvertently pulled nodes introduced by changeset 52045926, the intended goal there being two public transport nodes north.
The other node (commented in note 1180126) was incompletely reverted, creating an almost-parallel way to the earlier version of extensive changeset 45013590 -- the diverging path does not merge at the barrier as in the fix-not-revert from Kommunikations-Dezifit-Syndrom in changeset 53636124 recently.
As I am in the midst of an extended Internet-free period, and my editor-of-choice is sub-optimal for fixes here when a partial revert(s) to restore the mistakes introduced by the first-mentioned changeset (leaving the autobus node changes intact), I'll not try to fix this meself.
Maybe later, after hours of learning and after many days of A Real Life (as if such a thing exists) with no 'net access.
