Gothenburg has the largest tram network in Europe. It is Sweden's second-largest city and is located at the mouth of the Göta River on the west coast of southern Sweden. The tram network has been regularly developed/upgraded as there is no metro system in operation. The tram lines in the suburbs do go through tunnels, where there is also one underground tram station. The trams and buses in Gothenburg are run by Göteborgs Spårvägar (known as Västtrafik).
