It's better for AMDEP to have excess capacity rather than a lack
of capacity uh~ and those 3 SP BSEP Wrights in AMDEP are
practically being used now as normal SP DDs. Any svc needs a DD
replacement, AM just use any of those 3 to do.
Ditto for 3355H in BNDEP.
I would like to say though,
that AFAIK 3354K is still SP too and not perm BN 17? I have never
seen that bus during Peak on Sv 17 for so many months though, but
yet i've seen it more often on Sv 12 than elsewhere. And when
'2615P' posted 3354K as perm BN 17 months back, there wasn't any
e-tt change to support that BSEP fleet add theory. So i think 3354K
is still SP instead of BN 17.
AMDEP and BNDEP can have additional capacity - not saying no.
But it could be with SBST SP buses. Why use BSEP buses for
this purpose? Anyway, nothing wrong w/ using BSEP buses also
because at the end it is better to have a bus deployed than
not.
Just that when BSEP was introduced, didn't expect buses to just
run around as and when SBST wants but would be added to specific
routes based on loading.
