context_page_description: The Bordeaux tramway network consists of three lines serving the city of Bordeaux in Aquitaine in southwestern France.
  The first line of Bordeaux's modern tramway opened on 21 December 2003; further extensions have increased the route length to 66.1 kilometres. The system is notable for using a ground-level power supply of the Alimentation par Sol system in the city centre. It has been operated by Keolis Bordeaux since 1 May 2009.
context_section_description: By demand of the Municipality of Bordeaux (CUB), part of the system uses ground-level power supply (APS). There is no overhead wire, and electric power to the tram is supplied by a center rail with only the portion directly under the tram electrically live. This prevents electrocution of pedestrians and animals. See the adjacent photograph.
