New shift on Service 911 spotted. Confirmed is new OS-Shift.
This shift is slotted between the shifts of TIB1139K and TIB465A.
No perm bus on this shift, but as far as I seen only Service 963
buses have been used (TIB971E for the first day, TIB632J, TIB832Z
for 2 days, TIB726Y, TIB545C, TIB489G)
So the timing for now is like this:
TIB1139K, Service 963
x-over, TIB465A
The shift started last Wednesday, and didn't operate on last
Friday.
