The ETR 460 is a tilting
Tilting train
A tilting train is a train that has a mechanism enabling increased speed on regular rail tracks. As a train rounds a curve at speed, objects inside the train experience centrifugal force. This can cause packages to slide about or seated passengers to feel squashed by the outboard armrest due to...

 service on several routes all over the country.

The trainset has the ability of tilt by an 8° max angle when taking the corner to reduce the effect of the centrifugal force on the passengers. The passengers feel themselves comfortable even if the train fully takes advantage of the characteristics of the track thanks to the lightness of the construction (only 13.5 t (13.3 LT) / axle).
The use of this train does not demand particular modifications to the railroad but it is expensive in terms of maintenance of the rolling stock because of the complexity of the tilting system.

The hydraulic tilting system it is governed from two gyroscopes that are in the head cars. The curve is found on the base of the elevation of the external track.

ETR 460 are provided with 12 three-phase asynchronous motors (compared to the 16 in the ETR 450) placed n all cars, in order to improve capability in dealing with corners. Motors are controlled through inverters and GTO
