LGV南東線
In 1976 the French administration funded the TGV project, and construction of the LGV Sud-Est, the first high-speed line (), began shortly afterwards. The line was given the designation LN1, "" ("New Line 1"). After two pre-production trainsets (nicknamed "Patrick" and "Sophie") had been tested and substantially modified, the first production version was delivered on 25 April 1980.
