i just responding to your post.
3391C juz came into 12 for the past 3 days... infront of 3391C is
CDGE B9, behind it is KUB 8267X
but sv12 deployments not constant, can change daily, ie on diff
days, diff bus will appear on the time slots...
So let me ask you this: If 3391C just got newly deployed on the
roads (which seems like the case so far), and the first svc it ever
did was Sv 12 for the past 3 days (according to you), what makes
you so sure it's perm for Sv 12 then?
Don't forget that BNDEP still has 3354K & 3382D yet to be used
up as BSEP Wrights. And it's more logical to use them first, before
3391C is perm somewhere, isn't it?
It might be another case of 3354K happening again (it did Sv 17 on
the first few days, and someone else thought it was perm, but Sv 17
didn't get BSEP add nor was 3354K ever perm for Sv 17..).
Although, I'm not counting out the possibility of Sv 12 getting
a fleet add somewhere since the start of this year. The 7mins min
freq alr hints at this. But i'm just not fully convinced that 3391C
is the fleet add; the fleet add might be a non-BSEP bus
instead.
