The TGV Duplex is a French high-speed train of the TGV family, manufactured by Alstom, and operated by the French national railway company SNCF. They were the first TGV trainsets to use bi-level passenger carriages with a seating capacity of 508 passengers, increasing capacity on busy high-speed lines. While the TGV Duplex started as a small component of the TGV fleet, it has become one of the system's workhorses.
A total of 160 Duplex trainsets were built: the original order of 89 first constructed in 1995, an addtional 19 Réseau Duplex trainsets created as an extension of the TGV POS project in 2006, and 52 second-generation Dasye trainsets were first delivered in 2007 with revised traction motors and safety systems.
The Duplex design was further refined into the third generation Euroduplex.
