journey time. Nine sets were originally delivered as all first class. Set 88 was used as a test train for synchronous traction motors then subsequently rebuilt as a tri-voltage set and renumbered 118. Set 114 was sold to SBB in 1993 and a second set in 2005. In 1995, Set 38, one of the all first class sets, was converted to an extra postal set in addition to the existing 5 half-sets. In March 2012, a hired postal set, numbered 951, was taken to London to advertise the Euro Carex project. In February 2013 the TGV Lyria sets (110 to 118), designed for services to Switzerland, were taken out of service. These were replaced by TGV POS sets. In December 2019, all TGV Sud-Est sets were retired from service. In early 2020, a farewell service was run using the first production TGV set built. This train was painted in all 3 liveries that it used during its service. In service The TGV Sud-Est sets were originally used on services between Paris, Lyon, Marseille and other cities in the south-east of France. In 2013 there were still 55 sets in use on services to south-eastern France and on cross-country services. The remaining sets were replaced by TGV POS in late 2019. Fleet List Numbering The power cars were numbered as Class 23000 dual voltage locomotives, with the trailers being numbered according to the position in the set they were allocated to. So for Set XXX they would be numbered 123XXX, 223XXX, 323XXX and so on. The triple-voltage sets were numbered similarly but as Class 33000. Postal half sets were initially numbered P1–P5, later to P7. The power cars were numbered 923001—005, similarly the intermediate vehicles added a 9 in front of number. Names Many of the sets received names, principally of French communes, towns and cities. The names were carried on the two non-driving motor cars at each end of the articulated rake.
