Especially since there is
only 1 911E/187 crossover,
1 911E/169A/169/963E (911E/169A/169 in the morning,
963E in the evening, perm bus 427K). crossover that do not use
bendies at all (at least from what I had observed in the past
years).
And given the way of presentation, it looks like as if
TIB1140E had did 3 different shifts from 911 and 169 (e.g. 1
911E/169, 1 911 and 1 169 shift) in one single day ...
...
Italic : TIB981B replaces TIB1242U slot, not TIB427K
slot.
Underline :
TIB837K then could be doing s-shift then.
Bold : TIB1140E was spotted on 911 in the morning,
then was spotted on 169/911E in the evening.
