737 approaches the Rosensteingasse stop from the unusual direction of Taubergasse, having been diverted along Ottakringer Straße (the 44 route) due to the suspected unsafe building near Elterleinplatz referred to in an earlier caption.

737 is showing an unusual destination as the normal display for journeys to the depot is “Wattgasse Betr. Bhf. Hernals”.
