The story
On 30 October 2009, the whole network was reorganized, resulting in a lower number of lines operating with shorter headways. The reorganization of the network was suggested by the Plan de Movilidad Sostenible, 'Sustainable Mobility Plan', aimed at improving traffic and mobility in the city. In October 2010, some changes to the network were made, with additional changes in September 2012 and February 2013. A tenth line was added to the network in 2015.
