The tram network is an important addition to the train and subway. There are 9 tram lines with 10 minute intervals, daily around the clock seven days a week. For example the tram stops directly at station Friedrichstrasse, connects Alexanderplatz with the subway and trains and is the reliable transportation method for the Humboldt University students. An additional 13 tram lines exist in the outer areas of the city.
The adverts on the train carts are very visible by traffic participants since the track is in the middle of the road. For a long term advertisement you can choose between whole or partial coverage, for short term there is the 18/1 format billboard.
