Hillsbus is an Australian bus company that operates services in the Hills District of Sydney. Founded in 2004 when National Express merged its Glenorie Bus Company and Westbus (Hills District operations only) subsidiaries, it is today part of ComfortDelGro Australia. History First use of the Hillsbus name In 1996, Westbus established a separate Hillsbus brand to run express services from the Hills District to the Sydney CBD and North Sydney, initially via the Anzac Bridge and from 1997 via the M2 Hills Motorway. However, the Hillsbus brand seemed to have disappeared by the 2000s as these services were classified as Westbus rather than Hillsbus in early versions of the Westbus website. These Westbus services, however, were still referred to by Westbus as "Hills City Express". Current entity On 11 February 2002, Hillsbus was revived as a joint venture between Westbus and National Express' newly acquired Glenorie Bus Company, and introduced a new bus route 642 under the Hillsbus brand. This service linked Dural and the City via the M2 and was therefore known as a "M2 City" express service. On 8 July the same year, Hillsbus introduced three more M2 City routes 650, 652 and 654. According to the Hillsbus timetables, these Hillsbus services were operated by Glenorie, even though neither Westbus nor Glenorie buses were used. In December 2004, all Westbus routes operating out of Northmead and Seven Hills depots, as well as the rest of Glenorie Bus Company, were rebranded Hillsbus. At the same time, Hillsbus took over the operation of Harris Park Transport routes 620 - 630, following the latter ceasing operation. The services were transferred from Hillsbus to Sydney Buses on 28 January 2005. On 25 September 2005, after the purchase of Hillsbus by ComfortDelgro Cabcharge, routes 620, 625, 626, 627 and 630 were transferred back to Hillsbus. Despite the rebranding to Hillsbus, the new Hillsbus website was only launched in January 2006, about a year after the rebranding. The delay could be related to the debt of Westbus and was only resolved after the sale of Westbus and Hillsbus to CDC. After the launch of the new website, it still did not show any timetables of the former Glenorie-operated timetables until May/June 2006, and during this period, customers were asked to check the Glenorie website instead. When the Parramatta - Rouse Hill section of the North-West T-way opened on 10 March 2007, routes 730 (renumbered
