expand. The company added its last route in September 2005 when it was awarded a five-year contract by Southampton City Council to run the City-link service shuttle service in Southampton city centre. This nearly doubled their passenger numbers, adding one million passengers per annum. Uni-link also began trials of articulated buses and Wi-Fi on some of their fleet during 2007. Bluestar In 2008, local bus company Bluestar were named as the winners of the next ten-year contract to run the service. The service launched on 29 September 2008, coinciding with the new university year. The new company used a fleet composed mainly of new vehicles. In 2012, free Wi-Fi was installed on all Uni-link and Bluestar buses as a result of a £4.5 million investment from Transport for South Hampshire. In July 2013, Uni-link changed their smartcard system to 'The Key' smartcard that adheres to ITSO specifications and is currently used by several other companies owned by the Go-Ahead Group. The smartcard allowed Uni-link pass holders access onto Bluestar's central Southampton services (and vice versa) and allowed for greater deals with other Go South Coast operators. However it meant that the older cards, which included the University of Southampton student ID card, would not work with the new system leading to some controversy among the student population. In 2013, Bluestar ordered around 30 ADL Enviro400 double deckers, with two Scania CN230UB Omnicitys and five Wright Eclipse Urban 2's to mark their rebranding of the service from the old white and blue colour scheme to the new turquoise and blue-green colour scheme. In December 2017, during a joint announcement by Bluestar and the University of Southampton it was revealed that the contract between the University of Southampton and Bluestar for the latter to operate the service would be extended to run to 2028. To mark this, they made a £7m investment into new buses to replace the existing fleet by purchasing new ADL Enviro400 MMCs. Fleet Uni-link's current fleet is made up of thirty-two Alexander Dennis Enviro400 MMC double decker buses. These went into service in September 2018 and feature a refreshed turquoise green livery with different colour stripes down the side. They replace the double decker and single decker fleet used previously and are used on all routes. The old fleet has since been reallocated to Bluestar to help with passenger increase schemes and to replace older Bluestar buses. Liveries
