For info, SBST does not update the bus services in the website
in terms of NAC, PAC or FAC. In fact the info had not been updated
for a long time already, some of the info given are not accurate
one...
Service 11 reflects as PAC, but now can only have AC
buses.
Service 38 reflects as FAC, but always have NAC buses cameo.
Services 82, 103, 112, 113, 115, 158 reflects as FAC, but ever
have NAC buses before (not for now anymore 
)
Service 182 reflects as NAC, but all the while it is a mixture of
NAC and AC buses.
Service 191 reflects as NAC, but now it is more like FAC, after the
MK2s deregistered.
Feeder 275 reflects as NAC, but has been using Volvo MK4 AC
buses all the while.
Some JIS services are already officially PAC, but website still
showing as NAC status.
