Lower Emissions and Less Noise: First Atribo DMU for Trenitalia Driven by Voith RailPacks leaves PESA
A technical highlight is the way in which the engine is started with the aid of double layer capacitors, which replace the starting battery. The advantages of this solution are obvious: significantly lower weight, longer service life and, above all, outstanding cold start behavior.
The two Voith RailPacks enable the railcar to drive at speeds of up to 130 km/h. Their electronic control is linked to all other drive component control systems, resulting in just one common interface. This ensures that the RailPack is optimally integrated into the vehicle. The drive control, transmission of the operating conditions and relevant diagnostic procedures can therefore be easily carried out.
For the benefit of the passengers, Voith has also considerably reduced the noise levels of the cooling system. A specifically developed software program ensures that the fan speeds remain optimally adjusted. Thanks to this "Super Silent" solution, noise levels are significantly reduced while the train is at a station.
New ATR 220 Tr vehicles will be brought into service in the regions of Marche, Tuscany, Abruzzo, Campania and Calabria. The railcars are fitted with additional features such as air conditioning, Internet-ready devices, and a comprehensive passenger information system. With an overall length of 55.57 meters, they can hold up to 312 passengers.
Voith maintains a long-standing partnership with PESA. The very first Voith RailPack was developed for PESA in 2001. Since then, Voith has produced and delivered over 1,000 RailPacks with a wide output range, which are in operation in trains all over the world.
