Hello, My name is Marcus. I am 15 and I go to the Gwinnett School of Mathematics, Science, and Technology. I have used wikipedia extensively. I used to edit alot but... I forgot my old account. Now, i am just getting back into wikipedia. I still have alot to learn and I want to continue improving wikipedia.
The Dolderbahn is a 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.
