 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 <unk> 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 <unk> . The line received GSM @-@ R from 1 May 2005 . The same year , <unk> , the neighboring fjord to where Flåm is located , was inscribed as a World Heritage Site .
