There is another possibility.. Sv99 might be partial control by
SLBP now? since there is change of timetable this week... did any
of the new wrights spotted on other BBDEP service? there is two
persons spotted 3191 on Sv30 and another person spotted it on
Sv99.. so high chance that SLBP might control some duties of
Sv99?
For svc 99, so far I only know they deploy quite a number of VO3x
back on this service.
Maybe insufficient place in SLBP?
