Société des transports de Tunis

The Société des transports de Tunis or Transtu is the parastatal authority to manage public mass transit in the greater Tunis area (Grand Tunis). It supervises the bus network, the Métro léger de Tunis (a light railway system) and the TGM light rail link to La Marsa. Transtu was founded in 2003 when the Société nationale des transports (SNT) and the Société du métro léger de Tunis (SMLT) were combined. Annually Transtu handles about 460 million passagers. The longest line is currently line 47.
