It's always struck me that Euston is particularly badly designed, in
this respect. Given that the concourse is at a different level to the
platforms anyway, why not put the concourse *over* the platforms,
instead of well to the rear of them? That not only allows for multiple
routes down to each platform instead of just the one, but also makes
the walking distance from concourse to train considerably shorter and
gives you more concourse space.

It could also allow all platforms to be extended to 12 cars+, which
would be a real benefit.
