>>1987709>Mult megawatt 9kV step down is not easy, no way you're getting it within a couple hundred kg, to be robust enough to stick it on a train...Somehow, they managed to make 25kV->3kV->3phase conversion at ~4.4MW per power head while keeping the power head below 68t. All that with the superstructure weighing the majority of the vehicle, not the equipment. Thalys PBKA are quad system, if I recall.
Anon - it is fine to not know stuff.
