actually, i asked SBS last time about the duplication of 371
with 163 a few years back. it was said that in the fernvale area,
pax taking 163 will pay 83 cents, while 371 will costs 63 cents.
the presence of 371, a feeder svc, is to let passengers pay the
minimum to get to the town centre. However, now, 371 is withdrawn,
and 163A (wuich i never seen it), replaces 371 exactly. the fares
to fernvale on 163 were also subsequently adjusted to be fixed to
63 cents.. well well.... same as 227 and 17 i bedok..
