I think variety of length and height would be the best. It would
be a better mix so that they can run on routes that have different
demands. In HK almost all the routes can run double-decker buses,
even sv51 which runs to the highest point of HK(Tai Mo Shan/Route
TWISK) which a vehicle can pass through used double-deckers(MCW
Metrobus 9.7m M81-M88). 64K passed through Lam Kam Road(one-lane
dual-carriageway) and used 10.6m Dennis Tridents, restriction of
this route is the length problem, nothing longer than 10.6m.
Service 211 runs second-hand Dennis Darts from NWFB with 1 DM
Dennis Dart all along, and have received some Enviro500 cameos.
If length and height of bus cannot help, frequency is the next
best.
Wishlist:
ADL Enviro400, 500
DesignLine Olymbus :) -> It is an electric bus developed by
DesignLine. nearest would be Park Island. :)
That is Hong Kong.
In Singapore context, it is completely different. Non
standardisation means higher operating costs, which means lesser
profits for the operators, and this means that the shareholders'
interests, i.e, their shareholders payouts, will be affected. And
we all know who are these shareholders, directly or indirectly.
If I can get a standardised fleet that can accompolish the same
job of the non standardised fleet but at a lower operating cost,
why should I take the trouble to spend more money for different
maintance costs for different batches of different buses? Cost
increases means higher fares for commuters. Won't it translate more
complains and backlashes in future?
Bus companies in Singapore operates at their expense of
earning more profits for their "shareholders", not fulfilling the
whims and fancies of the bus fan community.
