VO3x from all over the island might get transferred over to SLBP to
deploy on JIS services as well as services like
182/192/193 when the NAC VO2x starts to go off. Then some
basic trunk services within the north and east areas might get the
newer EEV DDs in return...
In my opinion, priority for the new Wright B9TLs should be for
those trunk services (like you said in the north & east areas)
also currently having the K230UBs for ages but can't get the WAB
status due to their fleets requiring DDs, but there simply isn't
enough WAB DDs to go around currently.
Egs. Service 17 (had K230s for 2years+ already but still no WAB
status), Service 22 (need the new Wright B9TLs to replace the fleet
of majority ageing LO3xs).
Look around and you'll see more of such services, they'll be the
potential candidates to get the new Wright DDs first when it does
come out..
