SNCF TGV Sud-Est SNCF TGV Sud-Est The SNCF TGV Sud-Est or TGV-PSE is a French high speed TGV train built by Alstom and operated by SNCF, the French national railway company. It is a semi-permanently coupled electric multiple unit and was built for operation between Paris and the south-east of France. The TGV Sud-Est fleet was built between 1978 and 1988 and operated the first TGV service from Paris to Lyon in 1981. Currently there are 107 passenger sets operating, of which nine are tri-current (25 kV 50-60 Hz AC - French "lignes à grande vitesse", 1500 V DC - French "lignes classiques",
SNCF Class BB 30000 BB 30001 followed in 1974. SNCF Class BB 30000 The SNCF Class BB 30000 electric locomotives were built by Fives-Lille, CEM and MTE in 1961. They were the tri-current version of BB 9400 "Vespa" locomotives, of which they were closely derived, and inherited much of the knowledge of the experiences of BB 20004. With electrification of the mayor European axes pending in the late-1950s, SNCF engineers dreamed of a locomotive type which could operate of all 4 major European currents: 1.5 kV DC, 3 kV DC, and . Unfortunately, the technology to develop such kinds of locomotives wasn't advanced enough
