The Iore class was a cold-adapted and heavy-haul derivation from Adtranz's Octeon modular electric locomotive platform, which was launched in 1998 on the basis of Adtranz's latest models for Deutsche Bahn at the time.
Adtranz and later Bombardier Transportation conducted the final assembly of the locomotives at Kassel, Germany.
When Bombardier Transportation introduced the brand name TRAXX for its updated modular locomotive platform, the type designation TRAXX H80 AC was applicable to the Iore class, however, it was excluded from the TRAXX family by the time of the second batch order in 2007.
The manufacturer has also referred to the locomotive type as the Bombardier Kiruna.

Each Iore consists of twin units with one driver's cab at each.
They normally operate in fixed units of two, making a pair capable of hauling a 8,600-tonne (8,500-long-ton; 9,500-short-ton) ore train.
Technically an Iore section is also capable to operate as single locomotive, an option that is seldom used in operation.
The units are fed with 15 kV  16.7 Hz AC via a pantograph.
The power is transformed and then converted via a single water-cooled gate turn-off (GTO) thyristor based converter per bogie.
The converters belong to the Camilla family, which was developed by ABB's Swiss branch as successor for its oil-cooled converters, and found previous use in the FS Class E464.
The converters operate independently, with their own cooling and control systems and are shut down automatically in case of failure.
The converters consist of seven line-replaceable unit modules to minimize maintenance costs.
Each locomotive has six three-phase asynchronous alternating current traction motors, each rated at 918 kW (1,231 hp) and each powering a single axle.
This gives a Co′Co′ wheel arrangement.
The tractive effort of each locomotive is 600 kN (130,000 lbf) and the maximum dynamic braking effort is 375 kN (84,000 lbf).
There is also a boost function, allowing a temporary traction effort of 700 kN (160,000 lbf).
The units are capable of 80 km/h (50 mph) in single runs, 70 km/h (43 mph) with empty trains and 60 km/h (37 mph) with loaded trains.

The locomotives are 22.905 m (75 ft 1.8 in) long, 4.465 m (14 ft 7.8 in) tall and 2.950 m (9 ft 8.1 in) wide.
The distance between the bogie centers is 12.890 m (42 ft 3.5 in) and the bogie wheel-base is 1.920 m (6 ft 3.6 in).
The wheel diameter is 1.250 m (4 ft 1.2 in) when new and 1.150 m (3 ft 9.3 in) when worn.
Each locomotive weighs 180 tonnes (180 long tons; 200 short tons), of which 38 tonnes (37 long tons; 42 short tons) is electrical equipment.
Each locomotive has 30 tonnes (30 long tons; 33 short tons) of dead weight to increase the locomotive's weight to the maximum axle weight, and further weight increase has been achieved by making the walls 4 centimetres (1.6 in) wide with armored steel.
The extra wall thickness also provides for increased structural strength, to withstand collisions with snowdrifts and elk.
The sides of the walls were built as flat as possible to reduce the sticking of blowing snow and ice formation.

The auxiliary system is powered via a separate transformer winding feeding three independent insulated gate bipolar transistor (IGBT) converters each providing a three-phase 400 volt system.
The locomotive is designed with an open system architecture that can be adapted later.
Diagnostic information is available to the driver and can be sent to the control center via GSM-R. The locomotive has a large and bright cab with space for up to three people.
The second series of locomotives have an improved driver's chair, which has been retrofitted on the older trains.
The machine room has a center hallway.
All high-current equipment is located behind a door which can only be opened with a special key.
This key is locked in such a way that it cannot be accessed without grounding the locomotive, and similarly the locomotive cannot be ungrounded again until the key is back in place.
