Hmm, maybe I suspect...
TIB612S
(WLDEP 963R) - appeared on 963R every weekends
TIB1192E
(WLDEP SP ) to (WLDEP 913) - this bus always appear on
913.
For TIB612S the more correct version should have been WLDEP
901/587/963R. It still does 901/587 every morning. As for 963R
should be able to confirm after this weekend.
TIB1192E and TIB1191H had always been known to sub in MIA perms
from feeders .... ....
