I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
The Dolderbahn is rack railway in the Swiss city of Zurich. It has a length of 1.3 km (0.8 mi) and is located in Zurich's Hottingen and Fluntern suburbs on the south slope of the Adlisberg mountain. The lower terminus of the line is at Römerhof, around 1.5 km (0.9 mi) from the city centre, where it connects with lines 3 and 8 of the Zurich tramway. The upper terminus at Bergstation Dolderbahn is adjacent to the Dolder Grand Hotel and the Dolder recreation area. Two intermediate stations, at Titlisstrasse and Waldhaus Dolder, are also served.
