No please - they should be digging down in the tunnels. No light of
day.

Point of order - the deep level platforms at Paddington will have
daylight along their whole length, via a massive slot in the ground
above.

It would be good if a similar arrangement could be made for the
surface-level suburban platforms...

See latest liaR (I think - can't find any reference online but read it
in the last few days) - NR has agreed to rebuild the surface-level
suburban shed to the same style as the other spans, having failed to
get permission to knock it down Liverpool Street style...

Well I guess that is also good news, sort of. The suburban sid is
pretty crummy.

How will this work? I thought that the Crossrail platforms were to be
on the south side of Paddington under the old cab road?

Yes they are. They're going to build a long thin two storey high
"spine of light" (by which they mean skylight) between the cab road
and Eastbourne Terrace, which will be directly above the island
platform.

I suspect something like a linear 'sunpipe' would be quite effective
see:
http://www.sunpipe.co.uk

With the cost of enegy reducing the need for artificial light and
air-con can be very cost effective (as can regen braking)

As an aside I was suprised that the crossrail tunnels don't appear
'switchback' into the stations.
I'd like to be proved wrong as 'rising' into a station, and 'falling'
away is clearly the most efficient way of coverting kinetic energy into
potential energy and back again. Must be far more efficient than regen
braking.

Like that, but on a much much larger scale. The bottom of the sunpipe
will look like this:

That opening at the top of the picture will run the length of the
platforms and extend all the way up to ground level. Presumably
they've done the modeling to prove this will actually work.
