With the change of ownership, NSB also decided to replace the aging El 11 with El 17. The locomotives had been delivered in 1987 and were intended for express train service, but had been plagued with technical problems and were not considered reliable enough to operate as single locomotives. The six newest trains of the class were painted in a new green livery and branded as Flåmsbana rather than NSB. Older B3 carriages were renovated, given new panorama windows and painted in the same color scheme and taken into use on the line. In October 2000, NSB sold its shares in Flåm Utvikling to Aurland Ressursutvikling. The line received GSM-R from 1 May 2005. The same year, Nærøyfjord, the neighboring fjord to where Flåm is located, was inscribed as a World Heritage Site.
