>>975705>I also meant to hask, how much Freiburg system got "rationalized" in the 50s.Have this map from 1949. Line 5 and the remains of line 6 were closed 1959 and 1961. Haslach (5 south) was reopened on a very different route 2002-2004, Herdern (5 north) is a bus line today. The area of line 6 isn't even served by buses anymore today.
In 1986 a couple of lines around the central station were closed, as they were replaced by a new elevated section, which brings significant time savings from the western suburbs and also improved the interchanges to the trains.
