There are two DC/AC types. ÖBB class 1822 from the nineties was more or less a technical failure (lots of breakdowns, not enough power); the through train ambition was given up after a few years. The new ÖBB class 1216 (also "Taurus 3") would in theory be perfect, but Italian authorities have drawn out the certification process for higher speeds on DC lines. (Italy is introducing a new train control and signalling system.) Simple technical issues might be the reason, but blind protectionism, too.
