TIB961J was taking over TIB968R slot, not TIB959S.
TIB961J
[WL 969
WL 962].
TIB967T
[WL 969
WL 961].
TIB968R
[WL 962
WL 961].
TIB971E
[WL 969
WL SP].
You confirm already ah? so fast?
If that's the case, then
TIB 664S
WLDEP 187 - WLDEP 178
Covering the late 368Y's slot.
And also
TIB 571B
WLDEP 178 - WLDEP SP.
Sorry my mistake, As I believe this was an additional split
shift addition, If anyone saw this bus on 178, Should be spare, not
split shift if 670Z's slot gets shifted.
