30B was created together with the introduction of 30e, which is
after 31Aug05.
Jurong Industrial services are all NAC.
Other PAC services include 79, 92, 93, 94, 151, 154, 179, 182, 186,
192, 193, 242, 405.
The reason why SBST services are not labeled PAC or FAC because
SBST may decide to change any of the services to PAC or have NAC
buses as cameos like what muziq bus said. An example is sv79, a FAC
service with a NAC Mk2 added as perm recently, and sv242 with VO2x
as cameos.
