Please note that Miss Aggram used Lakeland coloured pencils and a sheet of A4 paper; but, for blogging purposes, fbb has redrawn using a very simple vector graphics program on his (t)rusty old confuser.
Di is using a number of other bits of cartography for reference; a good quality large scale London street map and TfL's area maps of which there are five. She is using the North West and the Central "quadrant" maps. But fbb is sure that the most important piece of supporting equipment is her "brain". She lives at Hampstead. She knows where and why the buses run!
Well done; quite correct; but look at his map! (Yes, Di! fbb obediently looked and remembered.) Hampstead Heath Station (Overground) is at the top with South End Green just below.The huge block (centre) is the Royal Free Hospital. The (purple) 268 runs along Haverstock Hill stopping at the end of Rowland Hill Street for the Hospital.
And it's not that far to walk back from Belsize Park if you're coming by Northern Line. TfL is not completely stupid. There is a sign to the station at the end of Pond Street ...
... although I'm not sure many people notice it.
fbb wonders, in passing, whether there is a sign to the Hospital at Belsize Park station? No doubt some knowledgeable blog commentator will know.
fbb's questioning continues. "TfL has added railway lines to its spider maps. Even I know that they are a mess. What would you do?"
It's not as difficult as TfL has made it; but then they have used outside contractors and a computer system; so there alway was a good chance of c*** results. But have another cuppa and one of my rock cakes and we'll have a go.
fbb is agog!
