It may not be a good idea of having Svcs 74 and 151 to be fully
aircon, if these 2 svcs are upgraded to fully aircon svc, then the
other svcs will be downgraded to partial aircon svc, they have too
many SP VO2xs and NAC Mk2s. If they want to use the SP without
making the FAC Trunk to PAC Trunk, I think svcs 112, 113, 315, 317,
325 or svcs 272, 273, 274, 275, 282, 284, 285 may be downgraded to
NAC svc
.
Then if like this, you'll complain other svcs, why they don't want
to use AC buses on these svcs.
