Presumably the best way they can see to reduce overcrowding on the 3-5
island. On the NR side the platform space is scarily narrow and very
difficult to move along at peak hours.

Hopefully they'll also get round to putting in some decent information - on
platforms 6 & 8 there are no NR monitors at the east end, with the result
that many passengers for Forest Gate have no idea if the peak hour train
pulling in stops there. (On platform announcements are rare and have a
tendency to get drowned out by TfL no smoking announcements, whilst the on
train announcements at peak hours are invariably over before the passengers
can actually get on. And to confused matters further the change from a train
timetable to a "next train to" sheet means that only the latter part of the
alphabet is shown at that end.)
