On 23 August 2007, LKAB ordered another four twin units, with delivery in 2010 and 2011, and costing €52 million. This will replace all remaining Dm3. After delivery, six locomotives are used from Kiruna to Luleå, and twenty are used from Kiruna to Narvik. By 2009, sufficient passing loops had been built along the whole line from Narvik to Luleå to allow all trains to operate with full capacity. By 2011, LKAB's will be able to replace all the Dm3, and convert all the ore trains to 68 cars. This will increase the capacity from 28 to 33 million tonnes per year, and at the same time reduce the number of departures per day from 21 to 15.
