in August 2000 and was extended in 2007. Line 3 now also runs on the former southern tracks of line 2, towards its terminus at Neustrie, an important transport hub near Nantes Atlantique Airport and Airbus facilities. A shuttle bus links the short distance between the airport and Neustrie giving an alternative to the "Navette Aéroport" linking downtown Nantes and Nantes Atlantique Airport. In 2011, 18.7 million journeys were made on the line making line 3 the third most used line on the network. It also serves as line 2 Hôtel Dieu, Nantes's main and largest hospital, Tour Bretagne and the Route de Vannes, a large superstore driving area spreading along several kilometers, coupled with a shopping mall and a hypermarket. Network expansion A connection between lines 1 and 2 is due to open in 2013 on the northern part of the network. The link will take the form of an extension of the branch of line 1 to Ranzay, opened in 2012, to Recteur Schmitt on line 2, creating two new stations, "Babinière sud" and "Martin Luther King". Rolling stock The fleet is composed of 91 tramcars of three types, two of which are the TFS-1 and the Adtranz Incentro. Both types serve all three lines. In 2011, Nantes also ordered eight CAF Urbos trams, with four options, from Spanish manufacturers CAF. Alstom TFS-1 Line 1 opened with 20 cars of type TFS-1, this being the original variant of the Alstom TFS design. TFS stands for Tramway Français Standard, and the intention was that this design would become the standard for subsequent French tramway systems. However, in the end the design was significantly revised for the Grenoble tramway, the second system to open, introducing the low-floor TFS-2 variant. Consequently, only Nantes has ever operated the TFS-1 variant. As built, the TFS-1 were double-ended, single-articulated 6-axle tramcars with a high floor and steep stepped access from low level boarding platforms. The tramcars built in this form were rebuilt, from 1992 onwards, with an added low-floor center section, thus becoming 8-axle double-articulated cars with a length of . Nantes subsequently bought further TFS-1 trams in this 8-axle configuration. Nantes now has 46 of these trams, built in 4 tranches from 1985 to 1994.
