點解城記唔大規模買兩膽volvo b9?

講真﹐可能真係車廠在車重方面計錯數﹐令到最後要拆一排座位﹐才可符合出牌的車重要求。
也有機會是政府當初話可以手鬆處理車重問題﹐但最後這個"手鬆"又無比車廠預期的多﹐所以超重而要cut位。


只好怪香港的出牌條例﹐相對 ...

各處響村各處例
你合唔到人規定
仲係人地錯？

E400 body + B9TL 陣要加錢俾ADL
如果有E400成set過, 平D又少D問題
點解要無啦啦將一架車既零件分家?
點解唔直接買一間廠既零件?
搞到麻麻煩煩.
仲未計富豪計錯車重, 壞車率高呢D麻煩野

仲有, 真係衰D講句
B9依家咁 ...

又唔好講到B9咁唔安全
睇番ADL果幾單都唔好得人地去邊

I think the whole saga of the 2-axle B9s were not just miscalculation, but Volvo and Wrightbus both made some fundamental errors:

- Volvo's decision to standardise the design of the 2-axle with the 3-axle design is one rather than using the proven UK-specification design, which leave very little room at the low floor area and compromise its weight distribution. Yes it has the benefit for a bigger fuel tank and share parts with its bigger sisters, but UK-spec B9s can do the same by using 2 tanks - 1 above the front axle which is standard on the UK-spec B9, and a supplementary tank just forward the offside rear axle. This design achieve a larger tankage whilst preserve a reasonable low floor area for the bus and provides better weight distribution, and it is seen with operators like First, Yorkshire Coastliner for some years already;
- Wrightbus have been too greedy by squeezing in far too many seats to the bus. Not only the additional seats weigh more, but the legroom are actually pretty poor as well. Put that into perspective, the B9s bought by Go-Ahead Group last year - the non-London ones - only has 43 seats upstairs instead of 47 as the HK pair were originally built, and they were built to pretty much the same length as well.

In any case, based on the rumour I have heard, we will be lucky to see another Volvo in HK in the short or medium term, let alone another 2-axle B9.

我唔係好熟B9既12米同兩輛既B9向機械既結構上差幾遠
但觀乎九記呢邊既12米B9好似冇咁多問題
而呢到亦不下於一個板友表示九記兩軸B9表現可以接受;甚至拍得住E400
咁點解偏偏城記呢部有問題到咁離譜呢?
會唔會係因為城 ...

而家連龍記o個幾部B9都虧到唔恨,
上斜慢,打冷震,水箱嘈乜都齊
(已經唔計行S線既先天性缺點:過迴旋處筅篩過E500好多好多)
我睇唔出城巴一定要買B9既理由,
特別城巴要既車係用黎行南區/山路

其實﹐2軸雙層冷氣車係一定over 香港的發牌要求的﹐如果唔係都唔會有ads 同 對面海10米利蘭出現。
明明2軸車的長度﹐都要加多一條車軸﹐增加機械的複雜性﹐增加營運成本。


今次引入2軸雙層冷氣車﹐事前巴士公司及車廠一定係得到政府表態﹐係會以手鬆處理﹐給予一些方便。
所以﹐2間車廠才明知車係一定過唔到發牌條例(以法例要求)﹐都會運幾部車來香港﹐給2間巴士公司試用。

問題係﹐政府又有無講手鬆處理﹐手鬆的標準又是多少? 即最多車重去到幾多
如果無﹐即係政府都無一個準確數字提供﹐一切按實際情況而定﹐這樣車廠自己都要靠估。
此情況下﹐都無得講問題及責任是在那一方面了。

香港路面根本就係窄 , 如果架架 2.55 最後咪又係增加問題風險
反而車重可以加就真既

我又好想知﹐E400 的確實闊度又是多少?
印象中﹐城巴都有貼 "肥仔証"的。


至於2.55米車在香港行走有無大問題?
我又同你講一樣野﹐我十多年前學車﹐跟駕駛學院﹐被迫上埋什麼理論課﹐上少一堂都唔得。
入面有講到法例要求一部車最多可闊2.5米(當然有額外的準許另計啦)﹐而一條標準的行車線﹐係最少闊3米。
你自己覺得在標準行車線上﹐又是否可以安全行到2.55米闊的車
註: 新建的高速公路﹐一條行車線係比3米闊的。

市區舊路之上﹐如彌敦道﹐大量E500﹐B9直梯巴士行走﹐部部都係2.55米闊﹐又有無出過問題?

當然﹐都有一些地方受環境所限﹐做唔到標準行車線闊度的。
但是E400都可以派入南區(淺水灣﹐赤柱一帶)﹐試問2.55米闊的巴士(包括旅遊巴)﹐又係唔係一個大問題?

I would say that still does not get away the fact that Volvo and Wrightbus have push the boat out a bit too much.

A while back I have done some back of the envelope calculation to work out the likely difference of the unladen weight of the HK-spec E400 and B9 - after the former arrives HK but before the latter comes out - based on the known weight of both types in London configuration and that of the HK-spec E400. My dead reckoning is that had Volvo and Wrightbus just upgrade a UK-spec B9 with an air-cond, and a secondary fuel tank, the weight difference between it and the E400 shall be fairly minimal - about 100-200kg in favour to the E400.

But then the B9 was changed more significantly to make it closer to the 3-axle sister, and with more seats fitted which adds weight, and not to mention the weight distribution is upset by ditching the fuel tank above the front axle in favour to a larger underfloor tank.

In my opinion, what Volvo and Wrightbus did to AVBWS1/7500 was overkilled.

如果根據petcity同NV58兩位的講法，九巴未來買車都係跟新城買ADL？

話時話，九巴未來兩三年都應該有唔少車要退，但係佢地除左已訂但未出牌果堆歐五ATEE
加埋61架AVBWU同28架AVC，就無落單訂新車啦？

講咩零件統一都係晒氣,最重要最main point其實好簡單:富豪開出黎單價貴過ADL,城巴揀平啲嘅,就係咁簡單
