Zurich Milchbuck tram stop, showing the exit from the tram subway from Schwamendingen. The surface route to Oerlikon bears left in the distance after passing over the exit, whilst the entrance to the subway bears right there, thus allowing the subway to use left hand running. This is necessary as it was built with centre platforms for use as part of a never complete U-Bahn system. The tracks diverging to the right nearer the camera are for a turning loop, not used in normal service.
