Hopefully striders, DMs and DM3500s. =)
They are a lot more comfortable than KUBs.... and also the laws
state that a high percentage has to be WAB buses for basic services
anyway, thus leaving 160 and 170 to be the only services (apart
from Express, Fast Forward, Chinatown Direct and RWS) to be
unaffected by the WAB regulation..
all buses would eventually be WAB
In any case, 170 is the sole service bet Kranji MRT/ Bt Timah
& Woodlands Ctr bi-directional (178 being Woodlands bound less
if considering tat Town Park bus stop across).
