in July 2016, running originally from Madingley Road Park & Ride (now: Eddington) via West Cambridge to Addenbrooke's Hospital. It is subsidised by the University of Cambridge and replaced the Uni4 service, formerly operated by Stagecoach in Cambridge. The service was rerouted between Cambridge railway station and Cambridge Biomedical Campus via the southern part of the Busway, starting 3 December 2016, after delivery of seven Wright Eclipse bodied Volvo B8RLEs fitted for use on the guided busway. On 21 June 2017 at approximately 15:48, a Cambridgeshire Guided Busway service, operated by Whippet, derailed near the entrance to the busway at Cambridge railway station. It was travelling towards Addenbrooke's Hospital. The bus crashed into a wall, with damage sustained to the driver's position but there were no serious injuries. Whippet initially blamed cyclists for the accident saying that they had caused the driver to swerve to avoid them. They later deleted those tweets, apologised to the cyclists and dismissed the driver for causing the crash by travelling above the speed limit on the entry to the busway. In addition to services C and U, in February 2019, Whippet launched a service P (for Pedigree), using the B7RLEs which previously operated on the C, between Cambridge City Centre and Addenbrooke's via the Guided Busway, thus duplicating Stagecoach's A and D services on this section. Service P lasted six months before being withdrawn in August 2019.
