Abstract
After recalling the limits of wheel/rail adhesion, discussing the pros and cons of three-phase motors in relation to d.c. motors and giving some ideas on how converters work, the author concludes that the various solutions being developed are aimed mainly at weight reduction and simplification of the different parts of the controls.
