I think they date from sometime shortly after when London Midland
relented and decided to allow PAYG on their fast trains from Watford
Jn to Euston (after London Overground's acceptance of PAYG on the DC
lines all the way to Watford Jn more or less forced their hand!).

The same day the overcrowding on certain problem trains got worse.
Shouldn't have been done until the next timetable change so that train
lengths could have been shuffled around to cope.

The other way of looking at it is that it might never have happened if
TfL had just waited instead of taking the initiative.
