Norway has trams in three cities: Oslo, Bergen and Trondheim.
Oslo's network is the largest, with about 130 km of line, consisting of six tram lines, numbers 11-19.
And for your information: They are not called trams in Norway, neither spårvagnar like in Sweden, but
the Norwegian word is Trikken.

A class SL79 "Trikken" turning onto the Geitabru bridge (goat bridge) in Oslo. These trams are from 1982-89. It is a German model by Düwag, but Düwag only built the ten first ones, after which ABB in Norway built by license the remaining batch. There are altogether 40 of these trams in use in Oslo.

Trondheim Trikken, Gråkallbanen
The city of Trondheim tried to close down all of its tram traffic in the 1980s, but almost by miracle one line, the 8,8 km Gråkallbanen remained alive in 1983. Now there are plans to again quickly expand the network. It is a meter gauge line, but with broad, 2,6 m wide trams. They have now 9 trams of the type TT class 8. Photo 21.8.2009 by Ilkka Siissalo.
The "Bybanen" (village rail) of the city Bergen is actually a new light rail system and not a pure tram. Bybanen uses full normal gauge (1435 mm) train tracks, so the coaches are much broader than those of typical trams. they have drivers cabs at both ends and doors on both sides. Today the Bybanen is just one long line bringing in people to the city center, but plans exist to extend the light rail system considerably in near future. The first part of Bybanen was opened in 2010. Currently it is just one line, 13 km long, with 20 stops. The trams themselves are a variant of Swiss Stadler Rail's standard Variobahn model.
