context_page_description: The Neoplan Centroliner is a series of low-floor transit buses which was first unveiled in 1997, and mainly built by Neoplan Bus GmbH for the European market. At the time when it was first released, it adopted contemporary technologies like Controller Area Network.
  The product range of Centroliner included: midibus, full-size/articulated single-decker, and three-axle double-decker, in different body lengths. The rigids had 1 door, 2 door or 3 doors whereas the articulated have 2 doors, 3 doors or 4 doors. After the acquisition of Neoplan by MAN AG subsidy MAN Nutzfahrzeuge AG, a new version of Centroliner full-size/articulated single-decker was launched, it was also known as Neoplan Centroliner Evolution and was based on MAN Lion's City with different bodywork. After restructuring of MAN's bus division in 2009, Neoplan is concentrating exclusively on luxury coaches and due to that, Centroliner was discontinued without Neoplan-branded successor. Instead, MAN promotes Lion's City as its successor.
context_section_description: KMB received the first Neoplan Centroliner in September 1998, after the test-drive of the 15 metres (49 ft) Neoplan Megashuttle in 1997.  A total of 20 Centroliner N4026/3s (fleet number AP1-AP20), equipped with Cummins M11-305E21 10.8 litres (659.1 cu in) straight six diesel engine and ZF Ecomat 5HP590 five-speed automatic transmission, entered service in August 1999.
  In 2000, KMB received 60 Centroliner N4426/3s, followed by 50 similar buses in 2000/2001.  They (AP21-AP130) were allocated to long-distance routes serving North/Yuen Long/Tuen Mun Districts.
  In April 2001, KMB acquired two Centroliner N4426/3s (AP131-AP132) which were fitted with MAN D2866 LOH-27 straight six common rail Euro 3 turbodiesel engines, and either a four-speed Voith DIWA864.3E or five-speed ZF Ecomat 5HP602C transmissions. They were coated with special metallic 'flip' paint, which shows different colours (mainly green and purple), depending on the angle of light reflection. They entered service in August 2001. One of them (AP131) was repainted in the standard KMB champagne gold livery in 2010.
  In 2002, KMB acquired a further 30 Centroliner N4426/3s (AP133-AP162) with MAN Euro 3 engines.  Two of them (fleet number AP144, AP159) are the world's first two transit buses to be equipped with six-speed automatic transmission.  The transmission is a modified ZF Ecomat 6HP602C.  They were the test buses of Eco-driveline (with large differential gear ratio, engine with high low-end torque and six-speed automatic gearbox).
  Withdrawal of the first batch of Neoplan Centroliners started in 2016. The last were retired in 2018.
  In May 2003, KMB received a NEOMAN Centroliner N4426/3 (APM1) with MAN ND313F chassis and straight staircase.  The width of the bus has increased from 2.50 metres (98.4 in) to  2.55 metres (100.4 in), and is equipped with MAN D2866 LUH-24 straight six engine, four-speed Voith DIWA864.3E transmission, and ventilated disc brakes on all wheels.  The bus was painted in gold with dark brown skirt, which is the standard livery for other straight-staircase low-floor buses such as TransBus Enviro500 and Wright-bodied Volvo Super Olympian.  It was registered in October 2003.  It has been criticised for its frequent breakdowns and extra difficulty in maintenance and so it has remained as a reserve bus since it entered service. This bus remained unique in KMB fleet and was retired on 16 January 2019.
