Yes. The Frecciarossa 1000 (ETR 1000) is an EMU, and the trainset’s coaches/cars are equipped with braking equipment as part of the integrated braking system—so it’s not “only the power cars” doing the braking.
So my first gut instinct is that one wagons breaks malfunctioned and suddenly applied breaking power since it was the last two wagons that went off.
That’s how every train works since this system was made mandatory in the US in 1893(!). Asymmetric breaking does not cause cars to come off. The joint is stronger than the breaking force. Anyway, we know it was a portion of the track that had a weld fracture.
