tfs

The Tramway Français Standard (TFS) is a type of tram designed and manufactured by Alstom for use on various tramway systems in France. The TFS is no longer in production, having been superseded by the Alstom Citadis range of tramcars.Two different models of the TFS were produced, both being articulated designs. The first model, the TFS-1, was built for the opening of the Nantes tram system in 1985. As built, these were single-articulated 6-axle tramcars with a high floor and steep stepped access from low level boarding platforms. All the tramcars built in this form have since been rebuilt with an added low-floor centre section, thus becoming 8-axle double-articulated cars. Nantes subsequently bought additional TFS-1 trams in this 8-axle configuration.For the opening of the Grenoble tram system, the TFS-2 variant was created. This was also a 6-axle tramcar, but had a different articulation mechanism with a very short central section carried on a four-wheel truck. This allowed a low floor to be carried through most of the length of the car and between the wheels of the central truck, although the sections over the outer bogies are still at a high level and accessed by three steps from the low-floor section. All the doors are within the low-floor section. The advantages of this layout ensured that all subsequent users of the TFS tramcar have adopted the TFS-2 variant.
