There were 4tph pre covid. But services got pulled off peak because of the need to save money. Plus Peckham Rye and Bromley South have a lot of other train services so not really sure what the issue is for those two.
Yes, but Stratford and Tottenham Hale have loads of services too, but I'm not going to say the 2tph West Anglia is remotely suitable. In fact, I'd say having loads of other services is a reason to improve the low frequency routes to encourage connections.
Right now South London's frequency and orbital links are dire, while North/West London has tubes all over the place as well as the NLL. While we put up with 2tph linking our major centres far too often (Peckham-Lewisham-Bexleyheath-Dartford, Bromley-Catford-Peckham-Elephant, Orpington-Lewisham, Richmond-Kingston, Sutton-Wimbledon). All of these are busy bus routes for parts or several sections of their routes and having lived locally for 20 years, I know if you're going from Catford to Bromley, the first thing you think of are the 208/320 buses - that's the issue. TL is spread too thin, doing too much while not doing the job well.
