Uh, with the influx of the MANs, I suppose it still is SP~
if you see Wiki, it's kind of confusing. Wiki states 1392Y &
1399D out from Sv 169, but 1109Y 1178Y & 1438A going
in.
The issue is that, WLDEP only has that much of SP bendies to go
around to replace the Bendy slots. So I'm actually not surprised if
1178Y or even 778Y is stuck on Sv 169 as long-term cameos (or temp
replacements, depending on how you define it) for any of the Sv 169
Bendies or Rigids that are away on cameo..
And I think there's going to be more reshuffle among the depots
coming up soon. And also with so many of the bus fans going to
Yishun nowadays (for NS or whatever not), the Wiki page will be
messy for some time..
I can confirm that SMB1438A is replacing
SMB1399D. Seen it on 911E every weekday morning
departing at 06:34am from WRI. It is still seen on 169 during the
weekends too.
In fact I don't think TIB1178Y is a 169 permament bus.
