The SNCF TGV Sud-Est was a French high speed TGV train built by Alstom and Francorail-MTE and operated by SNCF, the French national railway company. A total of 111 trainsets were built between 1978 and 1988 for the first TGV service in France between Paris and Lyon which opened in 1981. The trainsets were semi-permanently coupled, consisting of two power cars (locomotives) and eight articulated passenger carriages, ten in the case of the tri-voltage sets. The trains were named after the Ligne à Grande Vitesse Sud-Est (Southeast high-speed line) that they first operated on. They were also referred to as TGV-PSE, an abbreviation of Paris Sud-Est.
