I expect the captive network by, let's say, 2050 or 2060 to look a bit like this:
HS2 as proposed (London-Birmingham-Manchester and Birmingham-Leeds)
Liverpool-Manchester-Leeds-Newcastle (allowing London/Birmingham trains to get to Liverpool and Newcastle)
Wigan-Preston-Carlisle-Falkirk and Edinburgh-Glasgow (so trains can get from any HS2 station bar Newcastle to Edinburgh and Glasgow, and classic compatibles can run through Falkirk to Stirling-Dundee-Aberdeen and to Stirling-Inverness bypassing the Central Belt)
Birmingham-Bristol-Cardiff-Swansea
Toton-London relief line (moves captives from Newcastle, York, Leeds, Sheffield and Toton and classics from Hull off the Birmingham-London line, and shortens their route to London saving 5-10 minutes on all those services)
Possibly a Bristol-Exeter-Plymouth line, but I don't expect so.
Possibly something in the East, connecting off the Toton-London relief to serve Norwich and/or Ipswich (and perhaps an intermediate station for Cambridge or Ely or somewhere)
London-Bristol will be so good on the ICEP service that it's tough to justify HS London-Bristol. You can run classic-compatibles from Paddington to Swansea on the HS track from Bristol-Swansea and the GWML Bristol-London.
Possibly something to connect the NE to Scotland, but I don't expect so.
There might be a case for London-Southampton-Bristol, which would provide a Southampton-Bristol connection that doesn't otherwise exist (both road and rail are terrible), and also would bring the line into London on a different route, allowing for a new out-of-city station (ie a Surrey Parkway) and perhaps then an OOC-Heathrow-Surrey Parkway-Gatwick(-Ashford?) connection.
Even with all this, there will still be classic-compatibles running to Hull, to Aberdeen and Inverness, to Holyhead and to Penzance. None of those are ever going to justify a captive line (except Holyhead if there's an Irish Sea Tunnel to Dublin, but not before the 2070s or so).
