I notice that the plug doors of some Volvo B10TL's exit
plug doors are not in very good condition. I boarded
SBS9813M today and when it was time for the exit plug doors to
open, the right door opened first and the left door opened a second
later. I believe plug doors are to open and close together. When
the doors of SBS9813M was closing, at
least both doors closed together. On a side note, the
doors closing chime for SBS9813M was of a different pitch from
SBS9820S but it still sounded nice.
Seriously, they cant be closing together. If they close together,
something is very wrong. No matter how it is close of open, there
will be a lag time. It only depends on how long the lag time is for
the other side of the door to respond.
The next time u take a Habit / Volgren bendy / Trident / VSO /
B10BLE / B9TL / L94UB / K230s. Take a closer look.
