What is a TGV Duplex?

TGV Duplex sets are often run with a single deck Réseau set or another Duplex set. The Duplex feasibility study was completed in 1987. In 1988, a full-scale mockup was built to gauge customer reactions to the bi-level concept, traditionally associated with commuter and regional rail rather than with high-speed intercity trains.

How many Dasye Duplex trains are there?

In June 2007, the SNCF ordered 25 additional Dasye Duplex trainsets. Part of this order is for 55 tri-current trains, a new type high-speed train, and two levels ( TGV 2N2) and a reserve engine, permitting a relationship between France and Germany or Switzerland; Alstom call this "Euroduplex".

What is a TGV Sud-Est trailer?

A TGV Sud-Est trailer was tested in revenue service with the inside furnished to simulate the lower floor of a bi-level arrangement, and later that year another TGV Sud-Est was modified to study the dynamic behavior of a train with a higher center of gravity.

When did TGV-2N come out?

Discussions with GEC-Alstom began soon after, and in July 1990 the company won the contract to build the "TGV-2N", as it was then known. The contract was finalized in early 1991, at which point the official order was made. The first tests of a bi-level trainset were in November 1994.
