Lilleaker is a light rail station on the Oslo Tramway. Located at Lilleaker in Ullern, it was the terminus of the Lilleaker Line when it was opened in 1919 by Kristiania Elektriske Sporvei as an extension of the Skøyen Line (Øraker was the original name). In 1924 the Lilleaker Line was extended twice into Bærum, first to Bekkestua and then to Avløs. During the schedule, SL95 trams operate the entire line 13 without any transfers needed. When a balloon loop was constructed at Lilleaker the single-directional trams could turn there.
