I am guessing but I expect the West Ruislip - Greenford reference is about raising track and junction capacity on this section. If throw in aspirations about through trains to West Ealing or Heathrow plus extra trains down the NNL to Old Oak Common on top of Chiltern's existing services you have a bottleneck in that area. North of W Ruislip is beyond TfL's remit so they'll leave that to the DfT to resolve.

I understand TfL want 6 tph to Crystal Palace and 6 tph to Clapham Junction via Peckham. That takes total tph to 20 on the ELL core. I think 24 tph is simply an infrastructure capacity aspiration. If you invest in signalling and control then you'd go to 24 tph using ATO. I think that is what TfL are referring to and it's been their view for quite a while. They have no public aspiration to take over any bits of Thameslink and, as said by Colin, the local campaigns in S London killed off any common sense about Thameslink's service pattern a long time ago.

Crossrail 3 is a SE to NW cross London tunnelled line. It's been mentioned as the next big intervention to try to "fix" rail capacity issues in SE London. Some Assembly politicians are naturally very keen on this and the TfL Commissioner has mentioned it. Beyond that there is no detail. TfL have to get CR2 to the starting blocks and I fear that is going to be immensely difficult.
