You know, I am going to get nightmares tonight just looking at
that burning bus. I can never put up with SBS Transit buses even
being damaged, let alone... 
And guys, I think we should really not speculate about the cause of
the fire until the investigation report is out; MS will then be
able to update us on this. Right now, the (second) most important
thing is to look for suitable replacement buses to replace the slot
for this bus (B9TLs?!).
I wonder, though, if they might salvage the reusable parts of this
bus and build a new one from it
. I think not too likely, though.
