為何第三代後置引擎巴士........

我就反而想知道，點解香港果d後置偈雙層巴士會跳左第二代
由第一代既Fleetline，至到第三代先再大量引入？

題外一問，第二代後置引擎巴士係唔係Titan還是Metropolitan

先謝

其實怎樣定義第1-3代的後置引擎巴士?
三者設計有什麼不同?
那些車屬第二代?

另外,  珍寶的水箱在哪裡?

珍寶水箱設於車尾

即是與現在的B9, Trident 一樣?
但點解會容易水滾?

第二代無響香港流行ge原因...
會唔會係因為當年CMB試Titan果陣唔係太滿意...
而且當時名廠為左照顧英國內部需求，已經無能力額外生產？
而且當時Titan太高科技...車價又高？

但係雞鴨出現前﹐MC、MB已在香港出現﹐而且看來比珍寶更
可靠﹐為何又有走回頭路呢? 要繞個圈到幾年後才再入第三代
後置引擎巴士。

I guess the likely reason is the Metrobus have a higher acquisition cost,
comparing to the relatively "low" technology Victories and Jubilants. One
other issue was MCW was still a new supplier in a HK market. Comparing
to Leyland, which have the history of Guy, Daimler etc under its belt at
that point (since nationalisation in 1960s), making it more difficult for
MCW to break in to the market in great number, esp. when Leyland move
in with the Victory 2. The same reasons also applied to Dennis with the
Dominator, but they cleverly move on with the Jubilant which, importantly,
secure a market foothold in HK which became vital to the company's
success in the following decades.

Another issue is, consider the problems both KMB and CMB had with the
Fleetline, I won't be surprised both are skeptic to these new products.
Whilst CMB was more open to have a try, it was probably deemed too
risky to take up these new buses in great number - just in case if things
go wrong like the Fleetlines.

So we enter 1978 with KMB and CMB placing orders after orders on the
Victory 2 and similar Jubilant. By the time when the last of the demons-
trator, 3BL1, entered service in later 1981, KMB, for example, were
still busy bodying over 100 Gs still being delivered at that point. For the
matter, the final Gs did not enter service until Feb 1983, and the first
batch of the new rear engine bus (BLs and Ms) started to come on line
in the middle of the year. The gap is actually not as significant as when
we first look at the issue.

I think to answer your question, oxball, was that when the Metrobuses,
Dominators and Titan were bought by CMB, they were too expensive and
regarded as too risky to be bought in number, comparing to the Victories
and Jubilants. But by 1981, when MCW, Dennis and Leyland supplied new
demonstrators to HK, enough experience have been gained, esp. by
CMB to assure confidence that these vehicles are as good a workhorse
as they would expect, and the rest is history.

Apparently the definition comes from HK rather than Britain, because the
British definition on double decker generation was more time-related. For
instance, Fleetlines, Atlanteans (PDR1s and AN68/9) and Bristol VR (all
series) are widely regarded in Britain, as the 1st generation double decker.
Anything beyond that are not very clearly defined.

The HK definition says that the 1st generation deckers have rear radiator,
2nd generation have the radiator in other places (instead of front), and
3rd generation have the radiator at the front.

Now the only problem is, based on this definition, where do you draw a
line of chassis like Scania N112 or N113, which have mid-mounted radiator,
or the Dennis Arrow, which has a rear mount radiator. By the HK definition,
the Arrow should have been regarded as the same generation as the Fleet-
line, which is a design some 30 years older!

以前睇車主曾經講過，話當時英國車廠因為要應付英國本土既訂單，香港既巴士公司要訂車交貨期就要等好耐，法例又規定要用英國車，所以就要求一款設計簡單，交貨期快既車種，Leyland 就設計左一部由貨車底盤改進，參考 Victoria J 而成既 Victoria II，之後 Dennis 要照樣設計左 Jubilant，同時亦買入小量二手英國 DMS 以應付需求。

中巴由七十年代中開始，買車就定下兩個方向：一係為隧道線而買o既高載客量車種，
另一種係為內陸山路線而買o既中等客量並勝任山路o既車種。

由於隧道線客量增長比內陸線快好多，所以呢兩個買車方向之中， ...

謝謝大家的意見﹐很有啟發性
關於"爬山車"及"大容量車"的理論﹐細佬的朋友亦有提出﹐並指
出LV的出現是作替代LX的大爬山車地位﹐而重建後的LX則用於取
締M, S及LS。但雞車的催生者九巴﹐為何在80代前沒有考慮購入
第三代後置引擎巴士﹐而去訂製反潮流的雞車﹐會否是珍寶帶來
的問題與及九巴當年保守政策所致﹐又或是成本的問題呢?

P.S. 回Ricky兄: 快了快了
