丹尼士三叉戟 Dennis Trident

編號 Class:ATS

隨著丹尼士關閉了統治者之生產線,縱然為應付香港巴士公司訂單,特別增辟生產線繼續製造三車軸版之巨龍及禿鷹底盤,但另一邊廂,丹尼士也積極設計一款全新低地台巴士底盤─三叉戟,以取代上述兩款巴士。按照廠方之設計,三車軸版本三叉戟一共有三種長長度供用家選擇,包括最長之十二米,十一點三米及十點六米,及後因應新世界第一巴士公司之要求,再設計出十點三米版本。

九巴是香港,以至全球首家引入三叉戟的巴士公司,首架十二米樣板車早於一九九七年五月登陸香港,並於同年十一月投入服務,在之後因應發展需要,九巴引入大量十二米版三叉戟。而為了應付本港部份路窄多彎的路面,丹尼士亦於一九九九年向香港提供了一架配都普車身的十點六米三叉戟樣板車,並且由城巴購入。隨後新巴因應接辦中巴路線,亦訂購六十二架十點六米三叉戟,不過卻配用了亞歷山ALX500車身。反觀九巴,雖然九巴是擁有最多的十點六米三叉戟,但偏偏卻是最遲引進同型新車的巴士公司,首架十點六米三叉戟於一九九九年在九巴屯門車身裝嵌廠完成裝配後,隨於同年年尾投入服務。

九巴首批十點六米三叉戟訂單總數為五十部,全數裝配都普車身,在這批巴士完成裝配後,九巴所有新巴士都把電子路線牌列標準裝置,換句話說,這批三叉戟亦成為最後一批配用膠牌的新車。當新車陸續投入服務後,主力被派往一些客量稍低的路線,例如沙田廠的84M,86A,九龍灣廠的11D及13D。在較後時間,這些新力軍陸續被安排加入5C,46,108,234X及264M服務乘客。

為了接替車隊中車齡漸高的兩軸雙層巴士,例如利蘭奧林比安,都城嘉慕都城型,以及同廠的統治者,九巴再於二零零一年引入五十架十點六米三叉戟,不過配上改良版亞歷山大ALX500車身,以及使用Hanover電子路線牌箱。這批三叉戟陸陸續續由二零零零年夏季投入服務,並加入23M,64K,92,234X,273A及299路線行走。在這五十架三叉戟中,ATS96及97是配用歐三引擎的樣板車,並鬆上Kolibri漆油,成為「綠悠悠巴士」車隊成員,用以突出採用歐盟三型引擎之特點,並安排行走往返何文田及中環港澳碼頭的109路線。到了二零零二年,九巴購入最後一批同樣為數五十架的十點六米三叉戟,並且配用歐三引擎,當中二十架由亞歷山大裝配車身,而最後十架三叉戟亦改配ZF波箱,而非標準的福伊特。這批三叉戟投入服務後被安排行走17,29M,77K,109,117,269M,273A。而在二零零二年,九巴透過十點六米三叉戟,聯同同廠的短龍,實現了何文田區路線全空調服務的目標。

時至今日,十點六米三叉戟仍然活躍於不同九巴路線上,主要行走2B,2F,3M,5C,8A,14B,28,31M,45,46,64K,68A,81K,91M,283等路線。至於ATS96及97亦於二零一零年被翻油標準九巴低地台巴士的金色車身色彩,繼續行走109路線。二零一三年二月,九巴在ATS25(JK2480)裝上由Groba提供的橙色子路線牌作試驗。不幸地於二零零八年三月三十一日的天水圍車廠火災中ATS36被嚴重焚毀,成為第一架退役的十點六米丹尼士三叉戟。

After the closure of the production line of Dominator, although Dennis still produced the 3-axle version Dominator named as Dragon for KMB while Condor for CMB, Dennis was actively in designing a new low-floor bus chassis- Trident, as a replacement of the Dragon and Condor. According to Dennis, 3-axle Trident provides buyers with three different versions: 10.6m, 11.3m and 12m. Afterwards, 10.3m version were also available by request of NWFB.

KMB Is not only, but also the first bus operator in the world for testing Trident. A 12m demonstrator was arrived in May, 1997 and entered service in Nov., 1997. The trial of the Trident was satisfactoried and further purchased of Trident 12m was resulted. To cope with the narrow road conditions in Hong Kong, a 10.6m demonstrator with Duple Metsec bodywork was send to Hong Kong in 1999 and become 2700 of City Bus. To go one step further, NWFB placed an order of 62 Dennis Trident with Alexander ALX500 bodyworks in 1998 for the acquisition of the CMB networks since Sept.of the same year.

KMB followed the same step and 50 Dennis Trident received their Duple Metsec bodyworks in Tuen Mun assembly plant. The first sample was entered service in the end of 1999.The first batch Dennis Trident was first deployed on routes with relatively low demand like 84M, 86A in Sha Tin and 11D, 13D in Eastern Kowloon. More short wheel-based Tridents was then seen on 5C, 46, 108, 234X and 264M. This batch of Dennis Trident Is the last bus fitted with traditional plastic route display in the fleet.

The second batch of Dennis Trident 10.6m were introduced in the summer of 2000 as a result of the withdrawal of those aging Leyland Olympian, MCW Metrobus and Dennis Dominator. Starting from this batch, all Tridents were fitted with modified Alexander ALX500 bodyworks with Hanover electronic route display. Two of the batch, ATS96 and 97 were demonstrator of Euro 3 engine. Both of them painted with Kolibri and named as "GreenBus" to promote the features of using the Euro 3 engine. This batch of Trident were mainly seen on 23M, 64K, 92, 109, 234X, 273A and 299. In 2002, we saw the delivery of the last batch of 50 Trident 10.6m with Euro 3 engine and 20 of them were assembled by Alexander. ZF transmission units were chosen on the last 10 Dennis Tridents instead of Voith. This batch of Trident were mainly serving 17, 29M, 77K, 109, 117, 269M, 273A. One thing had to mention, the goal of fully air-conditioned service of Ho Man Tin District was achieved by the Dennis Trident together with the Baby Dragon in 2002.

All Dennis Trident 10.6m still actively service in 2B, 2F,3M, 5C, 8A, 14B, 28,31M, 45, 46, 64K, 68A,81K, 91M,283, etc. ATS96 and 97 were repainted with the champagne gold livery in 2010 and still serving route 109. A set of orange coloured LED route display from Gorba was fitted on ATS25(JK2480) for trial in Feb., 2013. ATS36 was claimed to be total loss in the serious fire accident of Tin Shui Wai Depot on 31 Mar, 2008.
