LGV南東線
Each train is formed of eight existing TGV Réseau single-deck carriages paired with new power cars, with a total power output of and a top speed of under 25 kV. The TGV Réseau power cars thus freed have been matched to newer TGV Duplex carriages to create TGV Réseau Duplex sets. This is because traffic on the LGV Est is expected to be less than on the heavily congested LGV Sud-Est.
