Mr SMB31X, if you believe 816X is not perm Sv 169 currently,
then may I suggest you provide a possible replacement that you see
consistently recently then? 
Otherwise, what your post just contain are just assumptions. It
doesn't help when you seemed to imply other people have no brains
to think, when your post also contained nothing constructive but
hot air it seems? 
I still see 816X consistently on Sv 169 over the past 2 weeks
though. Which although I agree with you that it wouldn't be perm in
the long term, it's still possible for them to use it as a
short-term replacement before whichever MAN / Enviro can be
found. 
First off, I am sorry if I come across as unreasonable picky or
bossy or whatever the reason may be, but right now the best option
is to wait til all the buses are de-registered before we find a
replacement, No point to observe until 3 weeks and yet the last
couple of weeks it is being kept inside only for it not to be
deployed.
Secondly at this rate the deregistration of the buses are going
and the coming in of the new MAN buses, It might not be wise to use
the buses that are about to go and they might keep the bus earlier
than expected ever since the plan to extend the buses that are
registered in late second half of 1995 backfired because of the
incoming MANs that are registered faster than expected and I don't
really wish to see all of your time and efforts wasted (especially
people who made an effort finding the replacements)for
redeployments, considering most of you are regulars observing 169
well, alot has changed ever since 169 moved to WLDEP and right now
everything is in an absolute mess (since most buses are about to go
and the extension backfired.)
Ever since in late 2012 when the scanias are de-registered,
everything seems to be getting out of hand in terms of fleet
deployments and the fleet management has totally been messed up
(notice when 961 went WAB, TIB490B TIB491Z TIB494R went and did
178, they extended the early'95 - 3Q 95 MB buses by half a year and
it went on to the CACs but it back fired for the october 95 - Jan
'96 MB buses only for them to go because the MANs are coming in
fast, and buses that are about to go might be kept inside the depot
not deployed at all for the remaining couple of weeks left.
I'm not commenting on things I haven't seen but I really hope
you get my point of why I am keeping 816X out of 169.
