TIB807Y
(KJDEP SP) > (KJDEP 77)
or (KJDEP 173)
Keep seeing it on 77, 173 and the B.B Feeders...
If it's 77 perm, then it should be replacing TIB613P...
If it's 173 perm, it should be replacing an OC or O405...
LOL there is a reason why it is called spare bus because it is
to replace perm bus in times of need, if it on every Bukit Batok
service then it is spare.
