丹尼士三叉戟十點三米 Dennis Trident 10.3m
四十架矮身版三叉戟巴士分作兩批進行車身裝嵌，首二十架新車(3301 - 3320)由英國Northern Counties進行車身裝嵌工作，餘下二十架新車則於新巴租用的中巴柴灣車廠，完成車身裝嵌。由於裝配地點及完成車身裝嵌時間有異，兩批巴士在投入服務時間上也有所出入，例如香港裝嵌車身的3321(JH8172)及3322(JH8311)，是緊隨首三架在英國裝嵌的新車(3301 - 3303)領牌投入服務。在投入服務初期，新巴替新車上層左邊車頭裝設樹檔，以適應行走港島路面環境需要，但已經於稍後時間拆除。十點三米三叉戟也是新巴車隊中，首批使用電子潛望鏡的巴士。這批巴士在投入服務時，曾經於車隊編號最後加上「L」字，至於箇中原因，最多人認為的答案是「L」代表矮車身(Low Bridge Body)，但正確與否則不得而知，而於二零零二年初開始，這個帶有「L」字的車隊編號已經不再被新巴採用。值得一提的地方是，除了3301曾披上宣傳十點三米三叉戟優點的條幅廣告外，3340也是新巴第五百架新巴士，並於車身上張貼相關宣傳廣告。
Still remember which bus model was the backbone of The Peak routes 15 and 15B during the CMB era? Yes, the answer is short wheel-based Daimler Fleetline (SF-class). As NWFB setting the goal for full air-conditioned operation after the taken over the franchised from CMB, the Fleetline would be replaced by the new, super low-floor and air-conditioned buses. Due to the high patronage of the 15-series routes, the Dennis Dart was considered to be not a suitable successor. To go one step further, headroom of the Mount Kellett Road Bridge prevented double decker with standard height bodywork from serving the Peak.
To solve the problem, NWFB jointly worked with Dennis and a tailor-made Trident 10.3m version was made. Dennis successfully supplied 40 Trident 10.3m to NWFB and they were the last bus model of the first 500 new buses for the acquisition of CMB networks. As their late commission, the SF-class Fleetline enjoying a longer service life than the long wheel-based Fleetline (LF-class) during the NWFB era.
The NWFB 10.3m Dennis Trident is the shortest Trident variant in Hong Kong and featured with an overall height of 4.17m Duple Metsec DM5000 low-bridge bodywork which can cope with the headroom of the Mount Kellett Road Bridge. They can be recognized easily with the rear route indicator box on the top of the upper deck window . The entrance is much narrow than other super low floor bus as a result of the shorter front overhang parts and the wheelchair ramp need to relocate to the exit. The specification of the 10.3m Trident are same as other members of the Trident family and made them not only suitable for running between the Peak but also route 9 and 14 serving Shek O and Stanley respectively. In addition, they can suitable for most routes operated by NWFB as a result of their flexibility and high capacity.
The body assembly works was taken place in UK and Hong Kong, the first of 20 (3301 - 3340) received their bodywork in Northern Counties plants while the remaining 20 were assembled in CMB Depot, Chai Wan. As the different assembly place and bodywork completion time, resulted in the commissioned time not follow with the fleet number, first batch of 10.3m Trident completed their registration is 3301 - 3303 and 3321 - 3322. During the early stage of their commission, tree guard was once fitted at the nearside front for operation on the Island. Moreover, electronic periscope was first fitted on the 10.3m Trident in NWFB fleet and their fleet number were classed as 33xxL which most think the letter "L" mean they are low bridge buses and around 2002, the letter "L" was removed from the fleet number. It should be mentioned that 3301 was used to promote features of 10.3m Trident and 3340 is the 500th new member of NWFB.
NWFB acquired a batch of 20 10.3m Trident in 2002 which comply with Euro 3 emission standard as a replacement of the second hand Dennis Dart (DC-class) from CMB and increase the carrying capacity of the fleet. This batch of Trident can be easily distinguished with their circular LED rear braking lights. All of them were entered service in mid of 2002 and when NWFB placed the order, Duple Metsec already become a member of Transbus International, also holding Walter Alexander and according to the group strategy, only Alexander product would be supplied for double decker. As there was no alternative product can be provided by Walter Alexander, this batch of 10.3m Trident still fitted with Duple Metsec DM5000 bodywork and to be the last Duple Metsec product in Hong Kong.
NWFB started looking for the successor of 10.3m Trident in 2015 and Alexander Dennis successfully won the order of 60 Enviro400 and started to deliver in the end of 2016. The 10.3m Trident still actively serving within the fleet along with the brand new Enviro400 until the end of 2017, we saw the first 40 10.3m Trident was gradually withdrawn from the fleet and the last Euro 2 sample was retired on 5 Mar., 2018. The remaining 10.3m Trident is expected to be retired soon, some of them would be converted to driver trainer while some of the fleet would be transferred to City Bus non-franchised sector as part of fleet replacement.
