it a waste, 857 always full of people from little india to
yishun. when it deployed on 143 the bus is fully use. if on 147
which is almost the same route as 143 at chinatown but 147 have mrt
cover it route. 143 things is people board the bus at bus stop far
from mrt station. even the route covered by mrt most of it like
147. 23 is the best but if LTA can extend 23 back to where it old
service route will be better.
Most 857 loads between Little India and Yishun are around 50-55
pax so even SDs seem okay. Hence, 857 haven't got more DDs after
the initial DD boom once SMRT took over.
Main DD loading for 857 is YCK Road to Khatib where buses take
100 pax. Here you also have 854, hence I think we see 50-60% DDs on
857 only.
