SBST will learn from SMRT on making 902 WAB. In next round, SBST
will increase its % of bus services even more by making 11, 91,
115, 191 WAB by putting 1 KUB or Citaro on it.
It will also announce 10 and 141 as WAB 
SBST doesn't need to be blatant like SMRT.Whats the use of
speeding Wab quotas when the scheduling,Maintenance and deployment
is poor?See how messy Yishun is for now?854 getting worse in
frequencies ever since Wldep part control..
