Then since Abbey Wood is the major destination then surely there has to be trains routes via the NK line then, both slow and semi fast
And as for axing Lewisham trains from the NK line that’s ridiculous, Lewisham is a useful interchange for trains to other parts of South London and different terminals like Victoria, you cannot seriously expect the 54 bus to replace the useful link between Woolwich & Lewisham?
6tph isn’t a bad deal, however if the inner stations do go 8tph then there has to be 2 extra tph for services further out to bring the line up to 10tph to balance out the needs of Medway/Gravesend users and inner SE London users
Best case scenario is to reroute Thameslink via Lewisham (since CX will most likely be axed anyway) and have 8tph via Greenwich.
Incorrect.
When Crossrail opens, a simple and regular 15-minutely service from Dartford to Abbey Wood for connections to the likes of the Docklands, the East (Shoreditch etc), the City, the West End and Heathrow will resolve most of these issues. Who needs to go to Lewisham, and what is their end game? Example: from Greenhithe to Victoria (no longer needs a service to Lewisham to connect as there is a direct service). From Slade Green and Erith to Peckham (change at Abbey Wood and Whitechapel). From Plumstead to Green Park (change at London Bridge instead of Lewisham and Victoria).
The only extremely small reason to go to Lewisham therefore becomes to go to the likes of Hayes, Catford, Orpington. Realistically, changing at London Bridge will provide more trains (many don't stop at Lewisham) or using local buses (they go from Deptford to Hither Green, Greenwich to Catford / Bellingham / New Cross / Peckham, Maze Hill to New Cross / Blackheath, Woolwich to Mottingham / St Mary Cray / Orpington / Beckenham Hill / Beckenham Jn / Elmers End / Ladywell / Crofton Park / Forest Hill etc.) will be worthwhile.
If you need Lewisham, just go to Greenwich and get the DLR. A 7-8 minutely service connecting with 5-10 minutely DLR is still better overall for certainty and speed than waiting round for a half-hourly direct train that's no longer turn up and go.
The only lip-service would need to be to a peak service. If you are going to route the Javelins off the Medway towns, Faversham (etc) to St Pancras with a 4tph frequency (much better) and need the Maidstone West to Abbey Wood train then the best-case scenario is an 8-car Metro train with SDO (see TSR2 requirements in the new franchise) that simply does Maidstone West, Snodland, Strood, Higham, Gravesend, Dartford, Abbey Wood, Woolwich Arsenal, Charlton, Blackheath, Lewisham, New Cross, London Bridge and Cannon Street; giving a direct train that people so massively need (apparently!) from Woolwich and Charlton to Lewisham as well as providing auxiliary capacity from Blackheath and Lewisham into London. Maidstone passengers will not sit on this comparatively slow train as they'll all be off at Abbey Wood and go to the likes of the Docklands, City and West End quickly; so it will empty out at Abbey Wood and create new capacity on the London end.
Lewisham to Victoria is hardly something the people of Erith, Plumstead and Woolwich actually care about when Crossrail will be vastly, vastly quicker. Assume Erith > Abbey Wood 6 mins; max 5 minute peak wait to Bond Street and Tottenham Court Road. Most people going to Victoria are not finishing their journey there: It's a useful staging post to go to Green Park and further West; Crossrail will take you to the likes of Tottenham Court Road (for Oxford Circus and Notting Hill), Bond Street (for Green Park, Baker Street and Westminster) and Paddington (for Earls Court, Fulham and Hammersmith) as well as going to the likes of Heathrow Airport.
I appreciate your viewpoint is not that of someone who has worked in the industry and knows passenger behaviour well but a service between Woolwich / Charlton and Blackheath / Lewisham is next to useless. Less than 1% of the passengers on the routes concerned probably need that train. This talk of the supposedly influential Charlton user group who want direct trains to Charing Cross are equally irrelevant. They should be told to bore off and change at London Bridge like normal people...!
