I can understand the need to change to Abt rack and raise the supply voltage to a more standard 1500 V DC but how is this being accommodated by the rolling stock? Is the same stock being used with perhaps changes to the motor groupings so that motors now operate with 2 in series to give 750V across each motor.? Surely this must mean a slight decrease in performance if the original supply was 850V DC, Presumably the motors are 850V motors.
