Well, I could list absolutely all of my changes, but that'd give away my potentially world-beating route (yeah, who am I trying to kid?

So I'll list a few in zone 1, and could anyone else add any that I should know about that are closed?
Warren Street,
Euston Square,
Great Portland Street,
Regents Park (ISTR this being closed - how long for - will it reopen before Shoreditch closes?),
Chiswick Park,
Gunnersbury,
Covent Garden,
Temple,
Bethnal Green,
Stepney Green.
And a creme egg to those who can guess my route!
