Last week the Subway station “Lerchenfelder Strasse” was closed. This improves the speed of the U2 so I will have to recalculate which is the fastest way to university.
The station was closed because it was only a few 100 meters to the next station “Volkstheater” and the stations are currently expanded for larger subways.
Also the rotation dock (Not sure if this is the right english word for “Wendeanlage”) at the U2 subway station Karlsplatz is operational again. This should also improve the speed of the U2.
