The real svs under these cate whereby using the old fare stage
system
3, 38, 60, 101, 112, 113, 163/ 163M, 181
There's no way svs like 228 would become 66M, simply because of
last bus (MRT) obligation and the first bus timing (As in is it
possible to let 66 to start at 0520 Bedok Reservoir towards Bedok
Int).
96, 133M aren't feeder services to begin with. They dun ply any
new town.
285 is there because it's nearer from Clementi to get to Pandan
Loop.
240 is the old Jurong Int issue.
334, 335 is a feeder service. 334 & 335's connection into
Jurong West traces back to pre BNL Int routing issue (Sv 98 linked
ppl at N2, N3, N4, N5 to Jurong Int).
Somemore dun gibe ideas leh, become 'M' they tell u become trunk
service no more 3.2km cap. LTA dun even know how to diff feeder and
trunk services out one.
