to 8160 tones. According to Adtranz’s project leader, Mr Erhard Heider, these are “up
to now the biggest locomotives in the world”.
Each 12-axle 45.80-m long locomotive weighs 300 tones, but is ballasted to
360 tones, which results in a 30-tonne axleload, LKAB also has 30-tonne axleload iron-
ore wagon on order from Transwerk, South Africa. The new locomotive will haul
68 wagons each carrying 100 tones of ore. This compares with existing trains of
52 wagons each carrying 80 tones.
The first unit is scheduled to complete acceptance trials by December 1 when it
will undergo further tests in revenue service. When these have been completed
satisfactorily, the second and third locomotives will be built and delivered. It has a
maximum speed of 80 km/h and a starting effort of 120 kN. The locomotive is powered
by modified traction motors, with water-cooled traction converters, and water-cooled
auxiliary converters.

EST OF THE LOCOMOTIVE
The locomotive is subjected to a series of adjusting tests in the factory which
includes test bed tests of the various machines, assembles and equipment of the
locomotive, tests of the locomotive under rheostatic load, as well as tests on the
Ministry of Railways’ test tracks.
The factory tests include tests of the diesel equipment, cooling devices of the
diesel, of the system of hydraulic drive, of the system of centralized air supply of the
electrical machines and apparatus, rectifier unit, etc.
Testbed checks of the diesel generator for stability of parameters, efficiency and
wear of the main units are made, as well as for stability of the physical and technical
properties of the oil and water, made according to the country’s industrial standards.
The tests are carried out for maximum permissible temperatures of the water and
oil.The adjusting tests in the factory, the rheostatic tests and trial runs of the locomotive
facilitate the establishing of the efficiency of all systems, equipment and the locomotive
as a whole. Factory tests prepare the locomotive for service tests on the railways.
The final stage of the factory tests of the new locomotive is service trial run with
a passenger or freight train. During the period of preparation of the locomotive a group
of specialists from the depot undergoes a special training course at the diesel
locomoticve plant and at other plants which manufacture components for the
locomotive. Locomotive and depot repair crews also undergo training courses
organized at the depot. Special groups for the engineers and technical staff are also
organized.
A group is organized at the depot called the Reliability Group whose task is the
continuous control of the locomotive working, its fuel and lubrication consumption and
