I thought that was the difference between Crossrail and TL - 10 car x
23 m and 12 car x 20 m.

The Crossrail Environmental Statement Vol 1 Ch 2, which was what I was
looking for before my earlier reply to Roger, has this to say:

"Rolling Stock Specification and Performance
2.4.12 The trains used for Crossrail will be 200 m long, formed from 10 cars
of 20 m in length.
The trains will be made up of two five-car units and will have a top speed
of 160 km/h.
The trains will draw power from overhead line systems. Their performance
will be
compatible with the project's requirement to operate 24 trains per hour
(tph) through the
central London stations.
2.4.13 The layout of each carriage will be designed to assist rapid boarding
and alighting in
the central area in order to minimise dwell times. Each carriage will have
at least two
sets of double doorways per side with wide set-backs and a combination of
four
abreast (as two plus two) and inward-facing seating. The trains will be
air-conditioned.
2.4.14 The Crossrail peak service pattern requires 58 trains of 10 cars each
formed from
116 five-car units..."

That's why I was asking Roger if the original spec had been changed, even if
not publicised.

Apologies for the crap formatting in previous post.
Also found the bit about station tunnel length that supports an original 20m
car length:

"At each station, the platform tunnels will be constructed to allow for a
future upgrade of platforms to 245 m for the operation of 240 m long 12-car
trains, should demand for Crossrail services necessitate this."

Ahh I see what you meant.

I don't recall anything ever than 23 m for Crossrail.

Indeed, not just for Crossrail stock procurement in its present form,
but right back to Chris Green NSE and 1000 Networker cars a year ad
finitum days when 16X were specified they were for cascade to
Crossrail by conversion to EMU (remove engines and transmissions from
16X cars, insert newly built intermediate emu motor coaches; don't ask
me about end gangways as I don't now).
