Alstom Euroduplex France

Euroduplex is the third generation of TGV very high speed trains being manufactured by Alstom. It is claimed to be the only double deck very high speed train which can meet the operational requirements of various European rail networks without any major changes in infrastructure.Euroduplex are suitable to operate on the French, German, Swiss and Luxembourg rail networks. The first set of trains was put into service in December 2011 when the French national railways SNCF inaugurated its Rhine Rhone LGV high speed rail line.The trains are a development over Alstoms TGV Duplex trains. Alstom designed the TGV Duplex train sets in the late 1980s when the need for transporting more passengers was arising.In 1987, Alstom came up with the design of a Duplex train set to increase passenger capacity without increasing the length of the train. Alstom partnered with SNCF to develop the model. The first generation TGV Duplex has a capacity of 510 seats, a 40% increase from that of a single level train. The number of bogies was reduced to 13 from the conventional 16, to decrease the mass of the train. Vibrations and noise were also reduced marginally.The second generation Duplex, called DASYE, includes a new asynchronous drive system derived from the POS system in the single level TGV.Most of the infrastructure of Euroduplex was adopted from the previous generation of trains. Euroduplex has a capacity to transport 1,020 passengers at a safe average speed of 320kmph. Its unique design provides the train with higher return per seat.Euroduplex is designed on an articulated train set model. The power systems are drawn from the previous generation trains.The train sets have fewer bogies than the other models, which reduces the rolling stock maintenance costs for the operators. Reduced noise and vibration provide optimal acoustic comfort. Lower weight and aerodynamic drag enable limited energy consumption.The signalling equipment on the train sets is compatible with networks across various European countries. The traction systems are adaptable to different voltages. Some of the train sets are suitable for use in Spain.The trains are a development over Alstoms TGV Duplex trains.

This design makes Euroduplex cheaper to buy and operate, and offers numerous other advantages, Reduced noise and vibration, for an optimal acoustic comfort,Fewer bogies which reduce maintenance costs,Greater strength, enhancing safety in the event of derailment.,Lower weight and aerodynamic drag which limit energy consumption.
