Volvo B9TL

The Volvo B9TL is a low-floor double-decker bus built by Volvo from 2002 until 2018. It superseded the Volvo Super Olympian and the Volvo B7TL. The 2-axle version has been superseded by the Volvo B5TL in 2014 and the 3-axle version has been superseded by the Volvo B8L in 2018.

Chassis

The Volvo B9TL chassis shared the same design of the Volvo B7TL. The key difference from both its predecessor, the Volvo Super Olympian and Volvo B7TL, was a new 9.3-litre engine originally designed by Renault. The radiator was located at the rear offside, similar to the smaller B7TL. The front module design was shared with other low-floor bus chassis built by Volvo, and independent suspension is fitted at the front axle (replaced by conventional front suspension after some years of production).

The B9TL was initially offered in three-axle format, and the two-axle variant was added in 2006 to replace the B7TL. The driveline comprises a Volvo D9A Euro III engine (rated at 300 bhp or 340 bhp), which was later replaced by the Volvo D9B Euro IV/V/EEV engine (using selective catalytic reduction technology; two versions were offered - the D9B260 rated at 260 bhp for two-axle version, and a higher powered D9B310, rated at 310 bhp, for three-axle version), and coupled to a ZF 5/6-speed gearbox. Volvo also offered the Voith four-speed gearbox as an alternative gearbox option.

The front wheels of the three-axle B9TL are usually supplied by Alcoa, but some buses (including the three prototypes) had all their wheels supplied by Alcoa.

There were rumours that the Euro III version B9TL that was once planned to being equipped with a German made MAN D2866 series engines with Voith DIWA 864.3E gearbox for Berlin. But since both sides are point out there have Difficulties in Mechanical Configuration, the B9TL version with MAN engine has been completely shelved permanently. This is fully explained that they have originally being expecting for a version to Berlin before they getting the final result that showed fail at the end.

Hong Kong

Kowloon Motor Bus

A Volvo B9TL prototype with a Volgren CR223LD body was delivered to Hong Kong in July 2003 for Kowloon Motor Bus (KMB) as a demonstrator for the ''Eco-Driveline'' concept. It was put into service in April 2004 and registered as MF5119.

In early 2004, a Volvo B9TL prototype with a facelifted version of the TransBus Enviro500 body arrived in Hong Kong. It had a slightly different front and rear design, and its rear route box was moved beneath the upper deck rear window. After TransBus International was renamed Alexander Dennis in May 2004, it became the only TransBus Enviro-series bus with a non-Dennis chassis.

Later in the same year, a Wright-bodied B9TL prototype was also delivered. The rear design of its Wright body was different from that of the Wright-bodied Volvo Super Olympian, with the number plate moved beneath (and a little to the right of) the rear route box.
In 2005 KMB ordered 63 B9TL chassis with Wright bodywork and 50 with Enviro500 bodies. The Wright-bodied buses entered service between 2005 and 2006, and the Enviro500-bodied buses entered service in late 2006/2007. These were followed by another 35 buses with Enviro500 bodywork, they entered service in 2007/2008.

''Bus & Coach Professional'' 26 August 2009 quickly followed by another 115, they have begun delivery as of early 2010. These were followed by an order for a further 115 Wright-bodied B9TLs in 2010. All these buses entered service between 2010 and 2012.

A 10.6-metre 2-axle B9TL was put into service by KMB in 2010. It was equipped with a Volvo D9B-310 engine and a ZF EcoLife 6AP1403B gearbox.

Starting from June 2017, some of the new B9TLs were painted with the new livery of red and silver stripes, with the motto "Heartbeat of the City" shown on the top of the vehicle. The last Wright-bodied 12-metre B9TL was put into service in August 2019.

KMB ordered three Gemilang bodied B9TLs in 2017. They were registered in September 2018 and entered service in March 2019.

As of July 2020, there are 953 Volvo B9TLs in service with KMB.

Long Win Bus operates 10 B9TL with Alexander Dennis Enviro500 bodywork which entered service in 2007/2008. All vehicles in this batch are almost identical to those with Kowloon Motor Bus.

Singapore

SBS Transit; Land Transport Authority

SBS Transit of Singapore placed an order for 150 B9TL chassis on 28 December 2004, then the largest single order, which were fitted with bodywork from ComfortDelGro Engineering (CDGE), part of SBS Transit's parent company. An additional order for 50 more chassis was placed in 2006 at a cost of S$29 million soon after putting its first B9TLs into operation, bringing the total fleet size to 200. These buses were delivered by October 2007. They were retrofitted with electronic destination displays in 2011 and 2012. Refurbishment began in 2018, except for one which was written off after being burnt at Ang Mo Kio Bus Depot fire in March 2010. These buses have been repainted into the Lush Green livery as well.

On 13 August 2009, SBS Transit announced an order of 150 Volvo B9TL, with Wright Eclipse Gemini 2 bodies, replacing 55 Leyland Olympian 3-Axles and 8 Volvo Olympian 2-Axles. Those were delivered between 13 September 2010 and 26 August 2011. One of the demonstrator was built by Wrightbus in August 2010, whereas all other buses were bodied by ComfortDelGro Engineering at Hougang.

On 6 September 2010, SBS Transit ordered another 300 Wright-bodied Volvo B9TLs, delivered between 21 September 2011 and 28 December 2012, replacing the rest of Leyland Olympian 3-Axles and 3 Volvo Olympian 3-Axles (Batch 1). 30 buses were delivered as low-entry, while the remaining 270 buses were delivered completely low-floor. In 2012, 30 of the low-floor buses were diverted to the Land Transport Authority's Bus Service Enhancement Programme (BSEP).

On 9 July 2012, SBS Transit ordered another 565 Wright-bodied Volvo B9TLs, delivered between 30 January 2013 and 18 June 2015, to replace most of their older buses, as well as fleet additions and introduction of new bus routes under the BSEP.

SBS Transit's final order of 415 Volvo B9TLs was announced on 1 July 2014, two years before the transition of Singapore's bus industry to the Land Transport Authority's (LTA) Bus Contracting Model in 2016 having only 94 units delivered. The orders for the remaining 321 Volvo B9TLs were subsequently inherited by the LTA for the BCM. An additional 176 Volvo B9TLs were also subsequently ordered by the LTA. The last batch of Volvo B9TLs to be delivered were registered on 27 December 2017.

; Early withdrawal
Between March and April 2021, SBS Transit retired 35 CDGE bodied B9TLs from revenue service due to fleet renewal and were replaced with 35 newer MAN ND323Fs. With the exception of two buses that were relegated to training duties, all of these buses were scrapped between April and July that year.

In January 2022, as part of a framework agreement for the transition of the Downtown Line to New Rail Financial Framework (NRFF) Version 2, 144 of the remaining Volvo B9TL CDGEs were retired from revenue service to be scrapped. These buses are being replaced by surplus buses leased by the Land Transport Authority. As such, only 20 Volvo B9TL CDGEs will continue revenue service until lifespan expiry in 2023.

Australia

Volgren bodied B9TLs were purchased by CDC Melbourne and Thompsons Bus Service.

Europe

United Kingdom

In three-axle form, the B9TL made its debut in the United Kingdom when Weavaway Travel of Newbury placed an order for six B9TL with East Lancs Myllennium Nordic bodywork in late 2004 and put them into service in April/May 2005. Since then, two more were sold to Roadliner of Poole and Provence Private Hire of St Albans for school contracts and commercial work.

The two-axle Volvo B9TL did not make its debut in the United Kingdom until the middle of 2006. The first demonstrator, with Wright Eclipse Gemini body, was delivered to London General in July 2006 for evaluation, it is used on route 11. The first order was secured from Delaine Buses for two examples with the new East Lancs Olympus bodywork. The first one, along with an Alexander Dennis Enviro400-bodied version, were unveiled in "Euro Bus Expo" show in November 2006.

Initial sales of the two-axle version were slow in Britain, particularly in London, after falling foul with the noise and capacity requirements imposed by Transport for London. Eventually orders were also received for the Volvo B9TLs by First London, Go-Ahead London and Metroline. The B9TL had success with Lothian Buses, FirstGroup
