Why does it not makes sense for them to order A95s?
Mechanically, the A22, A24 and A95 are similar, ie if you open the
engine compartment, they are the same except for a few minor
differences. Makes it easier for maintenance, you could order parts
in bulk, and have a easier time training mechanics, overall it
saves costs. And the driver's compartment is also similar, again
easier to train drivers on the buses.
Makes perfect sense for them to have the A95 in the fleet.
Completely valid points. However, SMRT already has the MMCs and
should just commit to it and not add a new bus type into its fleet,
however mechanically similar it is. SMRT having A22s and MMCs is
not any more complex than SBST having B9TLs and Citaros.
If the A95 had existerd earlier, I'm sure that they would have
gotten them instead of the MMCs. But now since they have gotten the
MMCs, better to stick to it than to buy yet another type of 'new'
bus model.
