I mean.......
Is TIB1010Y temporary replacing CSS185P or just merely
fleet addition?
Anyway, I happened to spot TIB1255H and TIB1010Y
on 981 while taking TIB818R on 169 to Yishun last Thursday,
but didn't manage to see another 981 bus.
More like replacing, since I haven't seen 185P on 981 in a long
time. Besides, the UDs are nearing their EOL, so a replacement is
due, eh?
