Semiconductor devices have now developed to the point where producing a three-phase supply of varying voltage and frequency aboard a train is quite feasible. The many advantages of the brushless three-phase induction motor have long been recognised by traction engineers, and this could well be the next major development in both diesel and electric motive power as work proceeds in several countries. Up to now, however, only pilot fleets of locomotives have been ordered and the cost of power conditioning equipment remains an obstacle to the general adoption of three-phase drives.
