Prior to the final negotiations, union representatives for the train drivers stated that Lok 2000 was their preference, and that NSB could expect a dispute if they chose a different model. The representatives stated that they were "tired of experimenting with Norwegian solutions". Another important aspect for NSB was that as much of the production as possible take place in Norway. The final negotiations were made with ABB/SLM and AEG and on 2 September, and NSB approved the agreement with ABB/SLM for a purchase of 22 units. The contract was signed on 27 September, and the 22 units cost approximately 700 million Norwegian krone.
