theres some flexibility on 98A. as mentioned, may change plates
to normal 98, may return to depot or interchange or labelled 98A
and loop back to jurong int on revenue.
i took a 98A towards Jurong Int before last year.. not sure bout
the politics now.
theres many ppl to/from jurong east to jurong east/west ave 1 and
up to corporation road, hence needs more buses. lesser ppl goes to
jurong port, so theres many 98A than 98
