Hi Alex.
What an interesting map / thread-about-the-map this is.

It would be interesting to see a series of how your various repositionings
and re-workings have progressed, maybe.

Now, I don't know much about where the lines go and that sort of thing, but
I do know that Willesden Green station is actually due north of Kensal
Green station (I used to live around there, and wandered around a bit), and
they're actually pretty close to each other. This is pretty easy to see on
Google Maps (or, I imagine, an A-Z or similar ;-).

I'm not sure how you'd be able to cram all those Bakerloo Line stations in
next to the Metropolitan line if you moved everything back towards the
east, but I guess that would be for you to work out, and the rest of us to
nitpick over...

Keep up the good work!
