The locomotives were originally built for the Norwegian State Railways (NSB) in 1967 to replace the NSB El 3 and NSB El 4 engines on Ofoten Line. The main task there is to pull heavy iron ore freight trains, and the El 15 is the most powerful engine which NSB has ever used.

History

Since the locomotives were to be operated in pairs, NSB considered only installing driver cabins on one end, but chose in the end to install them on both ends to allow the locomotives to operate more flexibly, including allowing them to operate passenger trains. The locomotives were numbered 15 2191 to 15 2196. 161-106-0 Hallsberg 2006 SRS
