Not that many different stocks now. The 4 sub-surface lines were given S7 or S8 stock according to platform length, and while it's entirely possible an S7 does sound different from an S8 I wouldn't count on it because these are basically the same train. So that's a change from 5 stocks (two A variants, two C variants and a D) across four lines to two (S7 and S8) in terms of the rolling stock. The deep tube lines will all get variations on the 2024 stock, likely in 2027 although I believe the announced date still clings to "late 2026" but for now are all distinct. |

I think that's a bit optimistic. Right now, the only thing that has confirmed orders is the replacement for the 1973 stock (Piccadilly line). The same order also has options for further trains which would cover the Bakerloo, Central and Waterloo & City lines, but somebody still needs to come up with the money for it.
For the Bakerloo line trains (1972 stock) that's probably going to happen, since those trains really are getting long in the tooth now, but for the Central/W&C line stock (1992 stock) there's currently a refurbishment programme underway, so depending on how that goes, those trains will probably continue running for a while further.
That still leaves the Northern and Jubilee lines (1995 and 1996 stock respectively), whose replacement trains, whenever they might happen, will probably need a new tender – it could be that whatever train gets selected then will be a close relative to the 2024 stock, but I don't think it's automatically a given.
And the Victoria line – that one only got new trains in 2009, so those will continue for quite a while further and will be the last ones due for replacement on the deep tubes.
