u have to understand that some svcs are now going towards a WAB
fleet.
and they don't have sufficient buses to meet that demand
now.
Till now I still dun understand why service 138 cannot get K230UBs.
I dun think the road conditions along Mandai Lake Road is that bad,
if not why 926/927 can accomodate with OC500LEs.
there is more than enough SP KUB to put on Sv138 if SBST want to
do so... the most likely reason will be "Mandai Road"... It is too
narrow.... i travelled several times behind the Sv138 mercs along
mandai road (near the upper thomson road section). the road are
quite narrow and the bus already cut into the opposite lane... i
think KUB are slightly wider....
