District line trains (D-stock) will increase to seven carriages
from their present six carriages but the overall train length will
remain virtually the same


The first part refers to S-stock, right?

Is it 7 carriages each the length of the C-stock ones, in which
case how are they going to solve the platform length issues? Or is
7S the same length as 6C, in which case the "increase of 17%" is
grossly misleading.


I don't know the actual car lengths for S-stock, but my understanding is
that they will be about the same as C-stock and A-stock (roughly 15 to
16 m length). The Evening Standard today said that "station platforms
on the Circle and Hammersmith & City lines will be extended for the
longer trains. A massive hole will be dug in Marylebone Road to
increase [sic] Baker Street platforms. Work is also needed at
Paddington and Bayswater stations."


I wonder if anyone's told Streets about the massive hole in the road...
that will require some serious planning!

Hopefully they won't work in the manner of the original cut and cover
builders, didn't they just dig first and then prop up any buildings that
started falling in to the 'cut'? It'll probably take as long to extend a
couple of platforms nowadays as it took to build the whole line
originally...

LUL trains can still run over 750V lines as they currently do on the
District and Bakerloo lines.


Yes , but arn't those lines set up so that 3rd rail stock gets 750V but
4 rail LU stock still only gets 630V?


No. The 3rd rail is +750V* and the 4th rail is 0V (and is bonded to
the running rails). If the 4th rail were at +120V, it would give the
arrangement you describe.

*Although someone has written on Wikipedia that it's actually 690V - a
"compromise" between the usual voltages for NR and LU stock.

to all who've written

Cars about 16m lonf. Longer than C stock, shorter than D stock.

7 car S stock about 20m longer than 6 car C stock - hence increased
capacity

Platforms will have to be extended but a minority might need a pair of
doors cut out

No articulation
