Someone please help to observe Sv 89's fleet in the coming week.
It received WAB status together with Sv 31 last week, but so far
it's still lacking 1-2 WABs (or at least that's what it seems from
Wiki) to hit the 60% for WAB status.
This is irregardless of whether I exlude Sv 89e buses from the
calculations, or include the Sv 89e buses in.
I have a feeling that both 6859B &
3940T are for HG 89. But I can't tell which are
the buses out yet. The DM3500s are still on 89 this past week.
Maybe 2762Y is going out with the expired JWEL ad, but I think one
of the Tridents should be out too. Someone just KIV for Sv 89 yeah,
thanks. 
someone already edited 3940 as perm sv89.. all Sv89e buses are
non-wab accordingly to ETT.. and it does not count in the WAB quota
for Sv89, as it supplement sv89..
but then if you look at the ETT, you can have 4 consecutive
nonwab slot and then follow by 3 more nonwab slots in one hour
(from the direction of Changi). guess it still need to take
sometime for HGDEP to allocate more WAB to sv89.. maybe the 4 Sv85
DDs are for sv89 initially, but were put on sv85 instead...
