Since BNDEP keeps having fleet swaps here and there everytime,
the years for the long perms might differ. For some of the east
side buses that have remained despite new WABs coming in (that i
can recall),
752P & 886L (BN 39) - Deployed on 39 since
launch, never left. Not sure if both were also from the AMDEP days
of 39?
858T (BN 359) - Still on 359 now despite its
siblings of 611M 663M 730C 841R 870G & countless others all
deregistered and gone already. Even more so due to the influx of
KUBs in recent years, this Mk3 is still actively serving its loyal
perm till now. Not sure for how many years already, but when i came
into this hobby in 2004, it was already on 359.
1972P (BN 21) - The only bus that remained on
21 till now despite new KUB & CDGE B9TLs entering since 2006.
All those from the same period all have gone elsewhere (think 986G,
987D, 2790R, 9811T, 9370Z, 9313P etc). Were there any previous
perms for this bus?
9354X & 9437R (BN 12) - Same as
9450B, remained on 12 till now even when CDGE B9s entered and
kicked out the rest of the VO3xs.
9629D & 9631X (BN 17) - Despite Wrights
& KUBs entering 17, these 2 have remained on 17 till now. I
know they have a certain previous perm previously (106 or
something), but IIRC when 17 first got DDs on its current route,
these 2 were the initial ones allocated and remained till
today.
Thanks if anyone could clarify on these buses 
752 886 went amdep and back.
858T was perm 31, went to 359 in 2002/2003 assuming no perm service
in between 31 & 359
1972 was spare. replaced 2627E when the latter was involved in an
accident. then 2627E went to perm 196e
