オスロ中心部にはトラムが2路線しかありませんが、西側と東側の両方へ広がっています。SL95は低床・両運転台、SL79は高床・片運転台です。山がちな地形と狭い道路のため、一部の路線は複雑な経路を通ります。（T-bane）
In the center of Oslo, there are only 2 tram lines, but they are spread both in the western and eastern side. SL95 is low-floor style with dual-headed, and SL79 is high floor and single-headed. Because of the mountainuous land and narrow roads, some lines take tricky routes. (T-bane)
