I agree with you, very troublesome. I think TNM will also have the
same situation once the PSDs are installed in a particular
time.
If EB/WB to CGL, won't be a problem, CGL train departs after the
time on the timetable, but if there's a train that opened it's
doors at particularly when the doors are closing, most likely the
TO will be kind enough to open again. If the other way round, then
might be a problem, or if it's a special timetable or peak hour or
etc.
