Mostly, LO2x. At that time, LO2xs never de-registered yet and
those LO3xs (AR 65 and BB 166) permer were still at BB/AR.
If I remembered correctly, SBS9107T and SBS9132U etc were the
LO3x perms fro 179 The rest were: Merczs and LO2xs
(majority).
After all LO2xs were went off, the VO2xs and LO3xs from
BBDEP/ARBP went and replaced them.
For BB/AR 65/166 side, mostly HG 85/865 permers went and
replaced them after 85 was withdrawn due to NEL ratilisation. (Did
those HG 85/865 permers became SP before x-fered to BBDEP?)
Correct me if got wrong, I am trying to post the most accurate
info. =) And this was what I had observed last time.
If I am not mistaken, VO2x were scattered around all the SBST
depots in the past. Services 70, 107, 153, 165, 186 etc used had
perm NAC VO2x.
With the withdrawal of some bus services due to NEL
ratilisation, those like 107 and 165 beneftted. All the NAC VO2x
were taken out and were replaced with the VO3x from the affected
services, hence upgraded to FAC.
The VO2x were all mass transferred from other SBST depots to
SLBP replacing all the LO2x which were bound for deregisteration in
end 2003.
