Trolley buses or trams? - A hot topic already in the early 20th century

Electric trolley buses are again discussed as a possibility in mass transit systems, also in Sweden. Some academic mass transit experts e.g. at the University of Lund seem to prefer modern trolley buses over street cars (which are favored by most politicians). 

In 1905 these trolley buses were introduced in Hamburg in Germany on the route Blankenese - Marienhöhe:

At the time there were plans to introduce this type of trolley buses also here in Helsingborg. However, nothing came of these plans. Instead the city opted for trams (which were in use until 1967). 

Now there are plans to reintroduce trams in Malmö, Lund and Helsingborg as early as 2018 or 2020. The city of Landskrona (also in Scania) is currently the only city in Sweden with trolley buses.
