【香港電車車款列表】
一直以來，電車沒有明確分代。雙層電車由開篷式改良至帆布上蓋到木頂，其實只是上一代電車的改良版。將電車以七代區分，並不全面。
由款式、年份和號碼著手，可以將電車分成以下六款：
1. 單層：1904年 (頭等 ∕三等)
2. 雙層 (開篷無頂)
3. 全密封雙層：1925年
4. 戰後式：1949年
5. 1987年系列
6. 鋁製電車：2011年
我們認為，以六個款式加上年份的分法，有助區分所有電車。
不過要從舊照片考究上世紀的電車號碼，難度極高，能清晰顯示車號的很少。
以12號為例，有加裝木頂上層的12號，60年代的拖卡亦有12號，和戰後式12號同時行走。若按照分七代，那拖卡是第幾代? 在欠缺年份的前提下，這種劃分明顯不夠全面。
按照六個款式的分法，12號可以分為：
1. 單層：1904年 (三等)
2. 雙層 (開篷無頂) ：無
3. 全密封雙層：1925年
4. 戰後式：1952年
5. 1987年系列
6. 鋁製電車：2016年
* 12號是第一部1987年系列電車
附件的列表，在六個款式的基礎上，進一步結合了年份、號碼、款式和製造商來說明電車歷年的演變。
例如68號的始祖是帆布上蓋、88號的始祖是戰前式、現時的120號是仿1949年款式、171號前身是冷氣電車…等等。除英國外，太古和黃埔船塢，過往是建造電車的合作企業。
至於千禧年製造的千禧電車，只有4部，不是全面取代現有車隊，因此不適用於分代。
[Fleet breakdown of HK Tramways]
Generally there is no specific/official “generation” categories on tramcars. As many of the cars in one generation were in fact just modifications of the previous, such as open top cars fitted with canvas roofs and then wooden roofs. This is not a clear classification to tram types.
Trams can be categorized in six types based on numbers, dates and styles. See below:
1. Single-deck: 1904 (1st class/3rd class)
2. Double-deck (open-top)
3. Double-deck fully enclosed: 1925
4. Post-war: 1949
5. 1987 series
6. 2011 Signature
We believe using ‘six-types and dates’ is able to categorize all the trams.
However, it’s difficult in researching precedent tram numbers from old photos due to rare clear views.
Wooden roof and trailers applied on no.12, of which trailer 12 run together with postwar 12 in 1960s. What “generation” belong to if according to “seven generations”? Obviously, it’s incomplete category without dates.
By using six types, tram 12 can be categorized:
1. Single-deck: 1904 (3rd class)
2. Double-deck (open-top): nil
3. Double-deck fully enclosed: 1925
4. Post-war: 1952
5. 1987 series
6. 2011 Signature: 2016
* 12 was the 1st tram of 1987 series
Based on six types of trams, we created a detailed database by dates, numbers, types and builders, to indicate the changes on fleet.
For instance, the ancestors of 68 and 88 were canvas top and prewar style, respectively, current 120 is replica of 1949 style, 171 was the 1st aircon tram, etc.. Worth noting that Taikoo and Whampoa dockyards were the former co-builders of HK Tramways.
As to the Millennium trams built in year 2000, it’s not applicable to categorize as “generation” as only four were built and not in place of the entire fleet.
