What you are saying applies to the entire country as well. Are
you suggesting that all buses in Singapore be standardised? I
understand where you are coming from on that. But the current
situation is that we do have multiple models (Citaro vs A22, B9TL
vs E500 vs A95). Given that situation, it's better to have all
operators at least familiar with all the types.
The problem arises mainly with the DD fleet, where there is a
more obvious imbalance. A22s are arguably not a very small
minority, but the E500s and A95s each are.
So what should we do with the minority fleet? Isn't that the
whole point?
For every new model introduced into an operator, that operator
has to spend money to induct drivers, mechanics, recovery crews,
operational staff, and others. If they choose not to train all
crew, either they have to impose operational restrictions or take a
chance.
As far as I know, TT is doing neither. Perhaps that might
explain the A95s being mothballed in the depot.
I am seeing things in the GCM/BCM that even Transperth, as bad
as it can be sometimes, knows it should not do.
