The tunnels have TWICE the cross section area of existing tube tunnels,
to allow a walkway!

Interesting. Of course, the DLR bored tunnels are similar. I wonder if the
Crossrail tunnels are also wide enough for a walkway, alongside the
mainline-size trains?

The larger tunnel will also reduce wind resistance and tunnel heating.


It looks like the public can get into a raised viewing platform over the
Battersea Power Station Station.

It would be nice if it's open to the public, but I suspect it isn't.
