Please do take note servcie 12 is currently operating a full
fleet B9TL . Yes, 9809B was a perm bus before but not anymore and
9833 was on svc 12 a short period of time before moving to Citybuzz
service and its very unlikely it's coming back to svc 12.
Btw, have you seen 9813M ? It's a perm 9 bus but there's a svc 12
writing on it .
For your info, BNdepot does not scribble numbers on the buses
anymore .
