Sv 162 isnt encouraged for ppl taking from YCK to city: it turns
into AMK ave 1, Bishan st 22 ( faster way is to use AMK ave 6 and
turn right at marymount road into Sn Ming) OR From AMK ave 6, all
the way down to marymount road, then to marymount link, and to
macritchie( same as 74,852)
for 170, theres competition from SJE and CW2, and by SBS syandards,
a potential 170e means it will have to call at more stops, which
wont go down well with commuters. also, the market is quite
satyurated with diluted passengers.
