Ouh ok, I also admit I've never seen SBS997A, SBS1688K and
SBS2888T in real life.
All green EDS SBST buses
.
I've seen all. SBS1688K is the most recent, seen it on 84 going
to Punggol Rd end.
SBS2888T was seen doing TRG in Sengkang when it was still HGDEP 85
then.
It was doing training on 163's route.
SBS997A seen it both when perm 62 and 83.
