The technological leadership of the train Italo
is based on the latest Alstom AGV technology in terms of high speed train, features a system of locomotion distributed throughout the different cars of the train, rather than being concentrated in the front and back locomotives. The space made available by the elimination of the locomotives is placed at the disposal of the passengers (increase of 20% in onboard capacity).
The structural architecture made possible by the distributed locomotion almost eliminates mush of the onboard vibration and noise, while attenuating the movements between cars, optimising the aerodynamics and guaranteeing maximum safety, in addition to reducing maintenance costs by 15%.
What is more, the combination of this technological innovation with composite materials and traction systems brought to even further heights of perfection has made it possible to lighten Italo
by approximately 70 tons, compared to the trains manufactured by the competition.
As a result, Italo
, the future train of NTV, offers extremely high environmental performance, with energy consumption reduced by 15%.
In detail, the primary advantages of the new Italo
train regard all aspects of performance: weight/power ratio, onboard space and comfort, energy consumption, safety and maintenance.
the bogies house synchronous engines that operate with permanent magnets and put out excellent levels of power, at the same time as they permit reduction in mass and volume, all to the benefit of energy savings. In fact, Italo
generates an unequalled weight/power ratio of 22.6 kW/ton, a figure 23% higher than the competition.
Onboard space and comfort
The elimination of the locomotives, replaced by the system of distributed locomotion, freed up space which was given over to the passengers, further increasing the liveability of the internal spaces (a 20% increase in the surface area).
In terms of width as well, with a body of 3 metres and an internal space of 2.75 metres, Italo
ranks as the best in its class in terms of liveability, providing increased comfort in terms of both seating and aisles, whose size allows passengers to move and pass by each other with ease, even when carrying bulky luggage.
Completing the optimisation of the space layout is the attentive handling of light (+15% window surfaces), ergonomics and the onboard equipment and accessories for passengers. In addition, travelling noise and vibration are limited by the deck, ensuring maximum comfort for passengers.
The train has been made easy to enter for all passengers, thanks to a floor that is a full 10 centimetres lower than those on trains built according to traditional architecture.
The care taken with ergonomics is also reflected in the driver’s cabin, designed in accordance with the international programs European Driver Desk and European Cabin. Drivers are able to control of the control station rapidly, making for optimal operation.
A final guarantee of elevated passenger comfort on Italo
is the low level of noise inside the train, made possible by numerous inventions in the field of aero-acoustics. In addition to the general reduction in travelling noise, a number of highly refined solutions, such as a body lining unaffected by pressure waves, will make it possible to limit the effect of air pressure on eardrums when passing through tunnels.
Thanks to the reduction in the number of bogies brought about by the new architecture of Italo
(resulting in less turbulence and, therefore, less resistance), together with the accurate aerodynamic features of the new design, especially high levels of environmental performance are possible, with energy consumption reduced by 15%. Compared to a TGV, the energy consumption per seat is roughly 30% lower.
is designed to guarantee maximum passenger safety. In the case of collision, passenger protection is guaranteed by the criteria used to set the dimensions of the body structure and by the energy absorbers, which fully satisfy European standards for passive safety. Furthermore, the configuration of the train as a whole, an approach that introduces a stronger link between the cars than is the case with conventional trains (the bodies are connected to each other with a bogie) provides the train with greater rigidity: resistance to side winds is improved, and, in the case of a derailment, the train does not crumple “accordion style”, unlike what would occur with a train lacking such links.
Bogies alone account for 35-40% of the total maintenance cost for a train, seeing that they contain the largest number of parts subject to wear. The reduction in the number of bogies, as compared to a classic train, makes possible not only increased passenger capacity but also a 30% per-seat reduction in the cost of maintenance.
