Do we know what these are for? Or were they just to
keep the Great British Public out before the line was open?

I suppose they allow one line to be open when the other isn't - which seems
fairly useful.

MetroGnome didn't say why the gates are interesting - one gate curves one
way and the other curves the other way. To grasp how bizarre that is you
have to see the gates shut, which they never are.

And at Stockwell, didn't the Northern Line swap a track with
the Victoria Line to enable cross-platform interchanges?

No, I don't think so.

# The Kingsway Subway

We drove through it on Wednesday night, but I
didn't find it easy to tell where was original tunnel,
and where was new construction.

The flat bits are original tunnel, the ramps are new construction.
