Though they stopped after only building 5 stations (out of which the first, Danziger Platz, is already closed and the next one, Rathaus, Hauptpost in this map, is going to replaced with a surface line)
Instead they (especially in Mannheim) built more new surface tram lines instead, which eventually were equipped with lowfloor vehicles.
