Nope, there isn't.
Apparently that guy(you know who you are, I just don't wan to
say it) is just reverting back edits or judging from
observations.
But AFAIK, before he edited as AR 14, someone stated it as AR 14
when I see it on 166 almost everyday. But after approx 2 weeks, I
see this bus cameoing on services like 5 and 165. I guess that bus
is SP rather than AR 14.
Plus I also noticed, SBS2687G only did 166 for 3 consec days
covering 3181S, that slot is merely replaced by random BBDEP
striders/dm3500, not SBS2687G
Me too also takes sv14 everyday and knows better than 3181S does
not perm sv14..yes correct, dont assume that 3181S perms AR 14 yet
when it is seen on it on and off. AR keeps on switching its buses
here and there nowadays.
Deployments are dynamic, really I find why anyone needs to argue
about things being changed and undone etc on sgwiki. It is just
from a person's observation just like you mentioned for 2687G that
seems to perm 166.
