What is the maximum design speed of the Italian ETR 1000 train?

What is the maximum design speed of the Italian ETR 1000 train? Its maximum design speed is 400 km/h.

The ETR 1000, marketed in Italy as the Frecciarossa 1000, was engineered for a 400 km/h design speed. That figure describes the train’s designed capability, not the speed normally permitted in everyday service. Infrastructure, signalling, safety rules and energy use determine the actual operating limit.

The train is an interoperable, multi-system electric train designed for international European routes. It can work with several railway electrification systems and signalling environments, allowing it to operate beyond Italy in countries including France, Germany, Spain, Austria and Switzerland.

The most common confusion is between design speed and commercial speed. ETR 1000 sets have been associated with a planned commercial speed of 360 km/h, while Italian infrastructure has generally limited regular Frecciarossa operation to 300 km/h. Thus, 400 km/h is correct for the wording “maximum design speed,” but not for routine timetable service.
