They look rather biological, does their smoothness reduce air
resistance? Or will they be cluttered up with pipes and wires?

You can see some of those tunnels being lined in this video:

Pity the trains won't be sized to match them. RER style double decker trains
would be perfect for this route. Given how many billions its cost for the
tunnels, I can't see why raising a few bridges on the pre-existing lines would
be such a big deal.
