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 15000 SNCF Class BB 15000 The SNCF class BB 15000 is a class of 25 kV 50 Hz electric locomotives built by Alsthom and MTE between 1971 and 1978. Initially 65 locomotives strong, the series was widely used on the whole French 25 kV network before losing services to TGV trains when the LGV Est went into service in 2007. In the mid-1960s, SNCF sought a new type of dual-current electric locomotives. As thyristor technology advanced rapidly, SNCF decided to adopt the new technology for a new series of locomotives, later known as the "Nez Cassés (Broken Noses, due to their
