171 will loop at where only 1 svc loops at currently, and also
where another service looped at before it was cut
Generally looping for longer services is a bad idea ⌠might as
well extend it to the nearest interchange. (Unless your definition
of "looping" refers to a 123/131-ish style looping that doesn't
involve the loop as a directional endpoint)
If it's BPJ MRT ⌠fine if it would be amended to terminate at
BPJ ITH. But there's currently three services (177, 180, 983)
looping there. 979/M as well if you count the end loops. May result
in ITH space constraint problems. Couldn't recall any past services
that used to loop there though.
If it's Hillview Rd ⌠should extend to Bt Batok via 177
route.
If it's Beauty World ⌠seriously just merge it with 41, can work
out a service swap between TT and SMRT separately.
If it's Keat Hong Close ⌠what the heck. Better to extend to Bt
Gombak and Bt Batok to bridge the MRT link and relieve load on
existing BB north services. Provided no serious duplication with
187.
Other looping points aren't visibly feasible.
