number of employees working on the ore logistics had been halved, and NSB stated that they did not believe there was much more room for higher efficiency. El 12 were retired in 1989 and 1990, and one twin unit has been preserved by Ofoten Museum. In December 1991, LKAB stated that they wanted to take over the operation of the ore trains from NSB and SJ. At the time, they were paying 0.15 Swedish krona (SEK) per tonne kilometer in Sweden and 0.30 Norwegian krone (NOK) per tonne kilometer in Norway, while comparable rates abroad were between SEK 0.03 and 0.10 per tonne kilometer. While SJ had several times during the 1980s agreed to reduce their rates, NSB had not offered the same, and was making a profit of NOK 60 to 70 million per year. LKAB claimed that taking over operations itself could save it SEK 200 million per year. In addition, they stated that they could save between SEK 50 to 100 million in auxiliary fields. LKAB had sent an application to Swedish authorities for permission to take over operations, and had received positive feedback from SJ. NSB, on the other hand, did not support a solution where they did not operate the trains themselves. LKAB stated that if an agreement with NSB could not be reached, they would shift all their transport to the Port of Luleå. In February 1992, a report ordered by Kiruna Municipality recommended that LKAB, SJ and NSB create a common company to operate the ore trains. At the same time, SJ stated that the consequence of LKAB taking over operation could be that passenger trains on the lines would be terminated. In April 1992, LKAB was awarded traffic rights by the Swedish Rail Administration. The rights also did not affect the Ofoten Line. The following day, SJ and NSB stated that they were considering establishing a joint venture that would take over the operations of the ore trains. In May, LKAB stated that Norway would, through its membership in the European Economic Area, be required to allow any train operator to run trains on a line, while this was rejected by NSB who stated that this only applied within the European Union, of which Norway was not a member. In late May, NSB stated that they were able to cut costs by 25% and that they would reduce the price to LKAB
