Not exactly as I understand it. They will all go via Bank instead of
some going via Charing Cross.

That's one way of putting it. The other is that all Charing X trains go
to Battersea, with additional trains running via Bank to Morden. Either
way, there will be more stock, and more trains running.

Are these new trains going to be more of the same design or will they be
completely new? One would hope the latter given the current 95 stock are
a 20 year old design.

They are required to be a "modern equivalent design" for both Jubilee
and Northern lines. Given the need to avoid excessively different
maintenance regimes and the continuation of the PFI rolliing stock
contract on the Northern I'd be astonished if Alstom didn't get the
work. They run the Northern Line's depots so how else is another
supplier going to provide trains that they then have to have Alstom
maintain? Lots of scope for IPR and warranty issues in that sort of
setup.

Alstom no longer maintain the Jubilee Line trains as the work was
brought back in house. However similar arguments about minimising
differences in maintenance practices, driver stock familiarity etc
still come in to play.

The bigger issue for any supplier will be DDA compliance with the
stock.

Are the original 95 and 96 stock not compliant with the post 2020 regs?

Would they not be grandfathered in?
