The NSB Type 89 railcar series are five diesel railcars procured second-hand from Sweden . They were bought by the Norwegian State Railways (NSB) to operate the Flekkefjordbane and given the series designation BM 89 .

prehistory

Flekkefjordbanen was opened in 1904 as a narrow-gauge railway with a gauge of 1067 mm. In 1944 the line was converted to standard gauge .

In the time when the line was narrow gauge, the trains ran with steam locomotives . When the line was rebuilt, only the track bed between Sira and Flekkefjord was widened for the standard-gauge tracks, but the existing tunnel cross-sections remained. This had consequences for the use of locomotives.

From 1941, Strømmens Værksted built a particularly light vehicle for passenger transport for routes with a light superstructure. This was referred to as Cmo type 7 , from 1942 as Cmdo type 7a and from 1956 as Bmdo type 87a and called NSB type 87 in the numbering plan from 1956 . Due to their small external dimensions, these trains could easily run in the restricted clearance profile . However, their economic lifespan ended between 1969 and 1981, they were shut down and scrapped.

Replacement vehicles that fit the clearance profile were found in Sweden . The vehicles of the local railcar series Y6 became redundant due to line closures, so that in 1981 the railcars Y7 1136 (built in 1957), Y7 1202 and 1205 (all built in 1958) were taken over by NSB as BM 89 01 to 03. Y7 1166 and 1182 (all built in 1958) followed in 1986 as BM 89 04 and 05.

When passenger traffic was discontinued, the vehicles became superfluous and the vehicles were handed over to the Dal – Västra Värmlands Järnväg museum railway and other museum railways.
