Since TfL want to take over all of the stopping services in South
London, I was wondering what is stopping them from extending the
Overground from Crystal Palace to Beckenham Junction on Sundays only. It
is a bit of a tight squeeze to run a quarter hourly service on the last
mile and a half which is singled, but I think it should be doable. I
don;t see how Southern could object when they run no service on this
branch on Sundays at all. Once the branch had 2tph Southern in the week
and 4tph LO on Sundays, Southern would be under a lot of pressure to
surrender the branch completely, and I don't think they'd resist.
