There was bus stop "Bachstraße" for route 813. But it is not listed anymore in the bus stop finder and the route of the line 813 on VRS website. I removed it. But it once existed, see: https://www.mapillary.com/app/?lat=50.625491666667&lng=6.9506472222222&z=19.102212437106672&pKey=482150006381226&focus=photo
