 On 22 November 2008, route X26 was doubled in frequency to every 30 minutes for most of the day, including Sundays, although the evening service remained hourly.To cover for the increase in PVR while new vehicles were prepared, Metrobus hired Mercedes-Benz O530s from Wealden PSV, delivered directly from original owner Quality Line.The Citaros have since been returned to Wealden PSV and replaced with Scania OmniCitys from the Crawley Fastway network, refurbished and painted red; these are two years older than the OmniCitys that previously worked on the route.
