Zürich's Oerlikon tram depot seen from an upper floor of the Swissotel Zürich. The depot is located above the Tram 2000 tram set. The new extension can be identified by its different roof colour. The main entrance and exit to the depot is from Tramstrasse (below the yellow construction crane) but there is also an exit into Wallisellenstrasse (under the tip of the red construction crane). The Sternen Oerlikon tram junction is just out of site behind the white building in the foreground.
