On 5 April 2025, at 14:30, the transportation network of the Nancy urban area STAN (Rèseau de Transport de l’Agglomeration Nanceienne – Keolis group) inaugurated the new T1 trolleybus line in Nancy (104,400 inhabitants in the urban area, 420,000 inhabitants in the conurbation).
The new trolleybus system replaces the TVR (Transport sur Voie Réservée), which came into service on 8 December 2000 and which in turn replaced the previous trolleybus network. The TVR stopped on 12 March 2023, to allow the new trolleybus to be built. The upgrade took 18 months to replace the previous overhead line and to remove the TVR’s track.

The conversion of the TVR line into a trolleybus line cost a total of € 47 million, approximately € 4.8 million per km. The new T1 line stretches 9,780 metres, is in service from Essey Mouzimprè to Vandoeuvre Brabois – Hopitaux, largely follows the route of the TVR system and has 23 stops in addition to the two terminuses, Some sections are without an overlead line, particularly in the city centre, which are travelled without problems by the new Hess trolleybuses.
