(This arrangement is shared with the SŽ series 310 in Slovenia, which are fundamentally the same train as the class 490, but built to standard gauge) in Its motor system is similar to that of an electric multiple unit because its pantograph is not located on a locomotive.

The cars are also built out of lighter materials that allow the train to move faster and put less stress on the tracks.

The power consumption of the Alaris trainset is considerably less than the Italian ETR 460, almost reduced by one third.

[citation needed] The tilting mechanism of the ETR 490 is quite similar to that of the second and third generation Pendolino series, controlled by gyroscopes, devices measuring oscillation, and speedometers.

The tilt is limited to eight degrees when fully activated when compared to a horizontal surface.
