Tramway de Nantes
The Nantes tramway is a tramway system located around the city of Nantes, France. The first tramway in Nantes opened in 1879 and closed in 1958 due to bombing damage during World War II, while the present tramway was re-introduced to the city in 1985....

 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
Tramway de Grenoble
The Grenoble tramway network is 35 km long, and comprises four lines: lines A, B, C and D. Line A was opened in 1987, line B in 1990, line C on 20 May 2006 and line D on October 2007. There previously existed a network of tramways in Grenoble, between 1894 and 1952...

, 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.

s and are 29.4 m (96.5 ft) long and 44.2 tonnes in weight. The cars cannot work as multiple units, although in case of an emergency two cars may be coupled using an emergency coupling system. With one tramcar not functioning, and braking diminished, speed is limited to 10 km/h (6.2 mph).

The tramcars have the following characteristics:
Length 29.4 m (96.5 ft)
width 2.3 m (7.5 ft)
height 3.36 m (11 ft)
Gross weight 44.2 tonnes
Power 550 kW
Speed 70 km/h (43.5 mph)
Passenger capacity 52/125

Car

The tramcar is built on a chassis 2.3 m (7.5 ft) wide joined by a central chassis on which is assembled a unique pantograph

s, one on each ends and one below the central portion.

Only the central parts of the cars have a lowered floor, at 34.5 cm (13.6 in) high to enable access to disabled users by four doors. The parts at both ends of the tramcars are built at 87.5 cm (34.4 in) high accessible by a small three-step staircase.

s are each equipped with a 275 kW electric motor. This gives the TFS a high acceleration, allowing its use on lines with steep gradients and/or frequent stops, and a top speed of 70 km/h (43.5 mph).

Operation

The TFS tramcar are one-person-operated. The driver is responsible for the closure of the doors. A single lever controls both acceleration and braking. The tramcars are equipped with land-train radios and ICS
