in short
1st order
In order to replace the well known Dm3 on the Ironline Kiruna-Narvik, a new locomotive was ordered in 1998 at ADtranz; the IORE H80AC. IORE stand for Iron Ore, the material the machines predominantly transport. One unit is composed out of two identical, fully-fledged singlecab Co'Co' locomotives coupled back-to-back permanently. They have one GTO frequency converter mounted per bogie. From the beginning the IORE locomotives were planned to be ballasted at 360 t: to be done 2006 after track reinforcement.

First pair was delivered in 2000 by ADtranz. The second pair, and following, were delivered after the company was taken-over by Bombardier transportation. The normal speed with a loaded train is 60 km/h. A IORE unit can haul up to 8400t trains. Compare this with the good old Dm3; 5200t.

In August 2007, the demand for iron ore was still increasing, making MTAB decide to order 4 additional pairs of locomotives, delivered in 2009 and 2010.

In april 2011, MTAB/LKAB decided to order another four double-locomotives. With these units the company wants to increase its transport capacity to 20 daily trains instead of the current 15 trains on the Malmbanan.

Our thanks goes out to Jean-Marc Allenbach, author of this section.

MTAB IORE: detailed information  
It is possible to disconnect two locomotives in about five minutes. From a driving cab, it is possible to control up to six units (also odd numbers!), the direction of others driving cabs has no relevance. In tractive mode, the driver can choose out of 41 different pseudosteps. At low speed the steps have a constant effort and up to about 16 km/h a constant power. The use of such a control mode is easier for heavy trains as control with effort reference. At very low speed during a short time, the driver can ask for a "42th" step at 700 kN for each unit.

The software allows a quiet transition between two steps. In braking mode, the driver has 30 steps at constant effort for a loaded train and 10 for an empty one. When hauling an iron ore train, fitted with with automatic couplings, the locomotives have their rigid buffers in retracted position, but for hauling conventional trains (max. 600 t), buffers can be replaced and an adapter for UIC-coupler can be installed in a very short time.

MTAB IORE: 2nd batch  
On 20.10.2009, the first locomotive of the second batch (no.119) was outshopped in Kassel and send on its way to Sweden. It arrived there three days later. The convoy consists of the locomotive (on temporary, lighter, bogies, so maximum axle weights during transport is not exceeded) and two carriages with the two final bogies. Locomotive and bogies will marry after their arrival in Sweden.

On 13.11.2009, the second unit (no.120) left Kassel, arriving on 17.11.2009. At that moment, unit 119 was almost completed, as the final assembly work on these locomotives is done locally in the work shops of Kiruna. Things that still need to be done after a units arrives in Sweden: replacing the transport bogies by motor bogies, placing ballast weight in the engine room, installing exterior details such as snowplough, hand rails, mirrors. The transformers get covered and an energy meter is installed. Then of course testing and final commissioning still has to be done.

On 26.01.2010, Klas Wahlberg (president of Bombardier Transportation AB) officially handed over the 119-120 to LKAB/MTAB, represented by its chief logictics, Goran Heikkilä.

On 13.08.2010, IORE 126 left Kassel, heading for Sweden, being the last one of its batch.
