context: Buses now provide the majority of local public transport. The main bus operators are First Southampton and Bluestar. Other operators include Brijan Tours, Stagecoach and Xelabus. The other large service provider is the Uni-link bus service (running from early in the morning to midnight), which was commissioned by the University of Southampton to provide transport from the university to the town. Previously run by Enterprise, it is now run by Bluestar. Free buses are provided by City-link'. The City-link runs from the Red Funnel ferry terminal at Town Quay to Central station via WestQuay and is operated by Bluestar. There is also a door-to-door minibus service called Southampton Dial a Ride, for residents who cannot access public transport. This is funded by the council and operated by SCA Support Services.
