For that matter, how will the tracks themselves be positioned? One
smart thing to do would be to run them down the centre of the
formation, so that in case patronage begins to pick up significantly, a
set of outside loops can be built at the stations and new platforms
added, to permit non-stopping of trains.

Funniest thing that I have read in ages, the prospect of the Eat London
Line being so busy it will need to be quadrupled. You would still have
the double track bottleneck to the south.
