yep, like how 45 take some bus from AMDEP. 
But the extension is serving the "birds dont lay egg" section
except Bedok South ave 3 part imo. I thought going round Bedok
North blk 85 hawker centre there more "value" for 48.
I've no idea why they decide to ply that stretch too. =/
What i'm thinking is the buses they will kope over from AR 48 to
BN. Apparently AMDEP still didn't transfer any of their KUBs over
to BNDEP after 292 & 403 went WAB, leaving 5006C as the only
KUB SP now in BN. So was thinking this decision might have
something to do with the buses going over to BN from AR
48.
Probably BNDEP will not want the Batch 1 Euro IVs, since those
had been under the West district all their lives (SL - HG - BB/AR),
and BN has no Batch 1 Euro IVs so far.
