I'm simply saying once SMRT has gotten the MMCs, they should
simply stick to it and not introduce yet another type of bus,
regardless of how similar it is to the buses it already has. You're
talking as if A95 is exactly the same as A22. Sure, many
similarities but of course not 100%. It is not right to buy A95s
simply because you already have A22s. Have MMCs as DDs, just stick
to one type of DD. Already SD fleet chapalang, OC, Citaro, A22,
don't further complicate the fleet of DDs. The A95 would have been
the best purchase if they had gotten it instead of the MMCs but
unfortunately, it didn't existed then. Best to remain decisive and
stick to what they already have.
So simply put, you don't have a practical (ie operational or
financial efficency) reason as to why SMRT should not buy the A95.
It reeks of a typical bus enthusiast mindset where bus companies
have to buy what the bus enthusiast wants.
The A95 doesn't complicate matters. Operationally, it is very
likely just treated the same as any other double decker, while
mechanically, its treated as another MAN, at most a simple
difference training could be done if they feel that is needed, but
definitely easier than doing a full training on a completely new
type like the Enviro 500.
*I wouldn't say the A95 is 100% similar to the A22, but rather,
upwards of 90%. Same D2066LUH engine, same ZF Ecolife
6AP2000B gearbox
plus all the other parts in the engine compartment. The differences
mainly lies in the additional axle parts and fuel tank location and
shape/size.
In the business world, you are free to choose any product to
suit your operational needs. You are not bound to a single
manufacturer. Perhaps the A95 trial went successful and SMRT found
it a better product to fit its needs, which is not suprising IMO as
personally, the build quality of the Enviro 500 leaves a lot to be
desired.
