Dasye and Euroduplex
Dasye is a contraction of Duplex Asynchronous ERTMS. The series has a similar design to the classic series Duplex, but internal changes have been made.
These trains are rolling the serial number "700". They feature a new powertrain with asynchronous motor of the same type as that of the motor TGV POS, and they also boarded the ERTMS. Train 701 was delivered in late 2006 and joined with section 619 Duplex Network (section delivered for processing and network duplex POS) for tests of preproduction. The train was delivered 701 complete on 14/02/2008.
In June 2007, the SNCF placed a large order to Alstom for 25 additional Dasye Duplex trainsets. Part of this order is for 55 trains tricourant a new type high-speed trains and 2 levels (RGV 2N) and a reserve engine, permitting the relationship between France and Germany or Switzerland; Alstom call this "Euroduplex".
These trains will strengthen the connections to the south, including the LGV Perpignan–Figueres, allowing the transit joint Franco-Spanish, completed in February 2009, used from December 2010 to two round trip Paris - Figueres and will be fully opened in 2013 for journeys Paris - Barcelona unchanged. This new infrastructure is innovative in France, because it is designed for high-speed train traffic, AVE and train Freight. It saves huge on travel time. The trains 200 and 600 series will not go to Spain because they are not equipped with ERTMS.
95 Euroduplex trains will also be used on the recently-opened Rhine-Rhône; the original 55, plus an additional 40 ordered by SNCF in April 2012.
The interior trim has reams of new colors (blue) and new interior (with electrical outlets at the seat in the 1st and 2nd class), the remaining facilities is very similar to those of duplex and an indicator of the speed of a TGV been installed in the car bar, above the bar.
