Those NAC DD buses (VO2x) have all been transferred to SLBP ever
since the LO2x were phased out, that's why only got SD NAC
buses.
Just bear with the NAC deployments on service 35 for a while
more. By end of this year all the NAC Scanias got to be phased out
and replaced with AC buses.
For your info, the SBST website is not updated in terms of
NAC, PAC and FAC.
(Eg. Feeder 275 stated NAC but the actual fleet is FAC)
