I just see a possibility, not predict. Since there was cameos
before, it might be possible that 36 might have Citaros in future.
Or else it might not, just as what the other guy says.
I think i posted this many pages before, but 36 hadn't got any
Citaro perms (probably might have only 1 or 2 in the future, but
not in the near future as far as we can see) because of the crush
loading at Orchard & Marina area, those crowds are like 24/7
every day in the week while the other airport services' load will
fluctuate according to weekdays/weekends or peak hours vs
non-peak.
Like I took 36 today from Dhoby Ghaut to Airport, the bus was fully
packed (yes it's a Sunday rmb) all the way till Marine Parade where
only then the crowd got lesser. The Citaros just can't fit
that much people at any one time.
The only possible reason from what I can see in it getting any
Citaros is to climb that steep incline from Marina Bay there up
onto Benjamin Sheares bridge, while 518 (which has Citaro perms)
use the other entry slip road to ECP from MBS instead which is more
flat compared to the one 36 uses (if i'm not mistaken). But from
what i could tell, the KUBs can still cope. I mean yes, it's
slightly slower in climbing that almost 45degree banking up onto
ECP and if BC not skilled enough the bus might downshift 2-3 gears
just to climb, but the KUBs (majority Euro Vs with the more
lethargic gearbox somemore) can still haul the bus up there.
