In terms of absolute cancelled train numbers , I guess we are now seeing a few hundred per month for Avanti right across their route network. Nobody could actually book with confidence right now.
That (and not shares in Arriva and Abellio, nor a suggestion that those TOCs are angels) is why I'm recommending people use the alternative options available for most of their journeys*, though anyone wanting some places between Warrington BQ and Carlisle inclusive don't have great options.
Those alternatives being, in case they're useful to anyone:
- Liverpool/Runcorn: LNR via Crewe
- North Wales: LNR or Chiltern to Brum, TfW to the Coast
- Manchester and local stations south thereof: EMR(+Northern) via Sheffield or LNR to Crewe then Northern/TfW/EMR
- Scotland: LNER(+ScotRail)
- Warrington/Wigan/Preston: see Manchester thence TfW or Northern, which is a bit roundabout so you may want to book to Crewe on LNR and see how Avanti are doing then
- Lancaster: also not great - as Manchester then Northern, or via Leeds, but both rather circuitous so you may want to risk Avanti from Crewe
- Oxenholme/Penrith: as Lancaster but worse as TPE aren't great either
- Carlisle: LNER then Northern
