The locomotives received transformers in 1947, which were installed in Oslo, and 2064 was delivered on 24 May.
In the 1970s, NSB started to consider replacement of the class. In 1971 and 1973, El 11 and El 13 were test-run on the line, and it was concluded that El 11 would be suitable with minor adjustments. However, the 1960s replacement of steam locomotives had caused a shortage of electric locomotives. Not until 1980 did NSB start the upgrade process of two El 11s.[13] From 1980s, only a single El 9 was stationed on the Flåm Line during winter, and the other two were used for local trains on the Bergen Line in Hallingdal. If the unit stationed in Flåm was out of order, it was replaced by a Class 64 unit. Lack of spare parts and limited reliability accelerated the need to replace the units in scheduled trains.[14] The first unit was taken into use on the Flåm Line in 1983 and the second in 1984. Two El 9s were transferred to Ål Station and Voss Station where they hauled work trains.[15] Unit 2062 was taken out of service in 1983.[16] The other two remained in regular service until 1988. Unit 2063 has been painted green and is on display at Flåm Station, while 2064 has retained the red color scheme and is stored at Tinnoset Station, belonging to the Norwegian Railway Museum.[14]
Specifications
The locomotives each have four NEBB EDTM423 motors, giving a combined power output of 712 kilowatts (955 hp).
The limit on axle load makes the locomotives small and compact. They weigh 48 tonnes (47 long tons; 53 short tons), and the total train weight is limited to 85 tonnes (84 long tons; 94 short tons). This also gives the trains a short length of 10.2 meters (33 ft).
