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 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 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 and each powering a single axle. This gives a Co′Co′ wheel arrangement. The tractive effort of each locomotive is and the maximum dynamic braking effort is . There is also a boost function, allowing a temporary traction effort of . The units are capable of in single runs, with empty trains and with loaded trains.
