“The U4 line currently only runs between Hütteldorf and Margaretengürtel or Karlsplatz and Heiligenstadt. Alternatively, please use lines 12 A, 59 A ”, Wiener Linien informed its passengers on Friday evening. The reason: There is a major police operation in the Pilgrimgasse underground station at the moment. According to initial information, two people are said to have illegally walked on the tracks.
The officials are currently still checking whether the rails can be released again. The malfunction should be remedied shortly.
