Personally I feel that these buses should at least last until 16
or 17 years, or at least till the state where it's totally not
suitable for revenue service. It's kinda wasted to just pull out
the bus that early when some are still suitable for revenue
service.
That wouldn't have made sense from SMRT's POV.
They are clearly working towards homogenising the fleet and
ending TIBS's cost-ineffective way of purchasing this and that in
small qtys.
Thus said, of course these small fleets will get retired before
life-span because you dont sai-ji-ka-chng replace your assets
right?
If you think its a pity, blame it on TIBS.
