Oceania Australia The first articulated bus in Australia operated in Canberra in the Australian Capital Territory in 1974. They remain in service for Transport Canberra serving both rapid and feeder routes. In Adelaide, articulated buses are used on the O-Bahn Busway, reaching speeds of 100 km/h. The first articulated buses to use it were the Mercedes-Benz O305G buses; however, three MAN SG280H buses are also equipped for O-Bahn use. In recent years, it has proven problematic to find suitable low-floor articulated buses to replace the 1984-manufactured Mercedes buses, because the design of the O-Bahn track unfortunately precludes the use of most modern articulated buses. Sydney has seen the operation of articulated buses for many years. Currently it operates a fleet of various models with eighty Volvo B12BLEA buses joining the Sydney Buses fleet in 2005 and 2006, increasing capacity along many of the busy corridors. A number of prototype vehicles were delivered in 2008 & 2009 to operate on Sydney Buses' first Metrobus route, the M10 from Leichhardt to Kingsford and Maroubra Junction. The buses feature different chassis, body types, and internal layouts. The articulated Volvo B12BLEA buses are fully wheelchair-accessible, air-conditioned, and have visual and audible next-stop passenger information systems installed. The buses feature air-conditioning, large electronic destination displays and cloth seating. Additionally, each bus features a stepless entry, which will assist less-mobile passengers. Flip-up seats in the front part of the bus allow easy accommodation for passengers in wheelchairs and with strollers and prams. In 2009-2010 150 new Volvo B12BLEA articulated buses have been introduced into the Sydney Buses fleet, many of these part of the expanded Metrobus program. Design Doors Articulated buses typically feature at least two and sometimes three curbside doors for passengers. Because the articulation joint is close behind the middle axle, usually four potential passenger door positions are possible on a single-articulated bus: Between
