Yes, and I have given accounts of practically empty travelling conditions at peak time on routes where there were once twice as many trains running.
One thing Southern are doing well is reviewing their operation to refocus capacity where it is needed, which can take some time to do.
Yes, but neither you nor I are an arbiter of saying whether the extra units were needed or not. It is fair to say that at least some of them weren't.
I think it is fair to say that 22 people in a carriage on a Tattenham Corner to London Bridge service leaving East Croydon does not justify a separate Tattenham Corner to London Victoria service running.
Travel patterns are different though, and 'fully recovered' is a misnomer because they evolve over time. As noted above, one of the things Southern appear to be doing well is recasting timetables in the light of 'recovery' rather than simply saying that the 2018 timetable should be set in stone.
Again, calling it 'cut to the bone' is just your view and not necessarily how the operator sees it. I think it is fair to say that the service is determined by the available rolling stock, but is that 'the bone'?
Yes of course there will be quiet trains at some times of day, there always were.
Also, it's quite sensible to remove peak extras where not required. However the Southern Region is based on all day long clock face timetables, and if these are now experiencing regular crowding as some are observing on here, then too much rolling stock has been withdrawn.
Not only is this bad for recovery now, it's also bad for the prospects of future growth.
