The city's public transport system was initially managed by the Société d'économie mixte des voyageurs de l'agglomération toulousaine (SEMVAT; literally the Toulouse Passengers' Mixed Economy Company), which was a company 80% owned by local government bodies and 20% privately owned.
After its final station, Basso-Cambo, is a carriage shed-workshop, which provides storage, maintenance and tests of the rolling stock for the whole of network.
The short platforms were lengthened from 2015 to 2019 and longer four carriage trains serve the whole line since early 2020, essentially doubling the capacity.
In January 2006, the Mayor of Toulouse, Jean-Luc Moudenc called for a fast decision on a southern extension of Line B.
This extension would include 2.5 km (1.6 mi) of line on viaduct, with a crossing of the Canal du Midi and the A61 autoroute, four stations and would terminate at Labège - Innopole.
The line has 25 stops: -Palais de Justice (Connection to Metro lines B)-Ile du Ramier - Fer à Cheval- Avenue de Muret - Croix de Pierre - Déodat de Séverac - Arènes (Connection to Metro line A and train line Arènes-Colomiers) - Hippodrome- Zénith - Cartoucherie - Purpan - Arênes Romaines - Ancely - Servanty - Guyenne - Pasteur - Relais - Marronniers - Patinoire - Grand Noble - Georges Brassens - Lycée - Beauzelle -Aéroconstellation
Both lines have a common section from southern terminus Palais de Justice to Ancely.
Since the upgrade, all of the 18 stations on line A are 52 metres (170 ft 7 in) long and can therefore handle four-car trains.
The trains have rubber tyres and use a third rail 750 V direct current electric supply.
They can climb slopes of up to 7%, reach a top speed of approximately 60 km/h (37 mph), and can operate on the line at a maximum frequency of 65 seconds.
In VAL 208 trains, the name of the next station and its connections are shown in each car on a panel of LEDs.
[9] The project has been canceled in 2014 due to the change of leadership of the city in favor of the new metro line.
In January 2006, the Mayor of Toulouse, Jean-Luc Moudenc called for a fast decision on a southern extension of Line B.
Plans for extension of the subway network to Saint-Simon were also vaguely mentioned by local representatives but never studied.
In December 2015, the transport authority SMTC unveiled the outline route for what was then called the Toulouse Aerospace Express, which will be the third metro line in the city.
