  • The idea of developing a universal traction system dates from 1965. It originated from the intention of solving the problem of building different types of diesel or electric engine locomotives with the greatest possible number of standard parts.

    The three types of locomotive, the diesel ones built by Brown Boveri, the BE 4/a test ones of the Swiss Federal Railways and the test unit of the German Federal Railways and the test unit of the basic material for the rest of the works for developing the three-phase traction system technique.

    Induction motors offer a series of advantages over the traditional commutation motor, and they are so important that the use of three-phase traction engines means an important step in the electric or diesel-electric traction field.

    The three-phase power transmission system developed by Brown Boveri uses an intermediate d.c. circuit, that is, the ondulator which supplies variable voltage to the three-phase engines is fed with a constant income voltage, and this voltage can be taken from different sources.

    On the basis of the experience obtained from the different vehicles developed and tested by Brown Boveri, the project of a high power locomotive could be started.

    The range of application of these locomotives goes from models for heavy loads at low speeds, to very fast trains. This wide range of applications makes this three-phase traction system a very interesting one.

    Costs are a very important item. If it were possible today to make a conventional locomotive with the same running and behavior features as a three-phase traction locomotive, there is no doubt that that vehicle would be far more expensive than the last one, without taking into account the servicing advantages offered by this last locomotive.
