I've only just joined the newsgroup after a long absence, so I don't
know what's been posted.

Franklin Jarrier has recently updated the London map with some minor
changes and additions - now v1.1

That is an outstanding map - though as a minor point of order, Shoreditch
station is listed as closing 22/12/2007 - I'm pretty sure it closed in
June/July 2006, while the rest of the ELL closed on the date you've
suggested? (anyone confirm?)
