Now that all platforms are barriered, it would be good if a route
between platform 11 and 12 could be opened up (maybe with barrier

11 & 12 are adjacent to each other, are they not? *Do you mean 10 &11?

Yes, I guess I do. I was thinking that there were four mainline
platforms rather than three.

I notice that the barrier between 7 and 8 seems to be left open now
but there is no access between 10 and 11. If there was access, it
would need to be someway down platform 11 given the Central Line
entrance and other facilities in this gap but I don't see why it
shouldn't be possible. Then again, perhaps the wall is too think to
put a hole in.
