Wondering now if anyone revisits the Sutton Loop lobbyists - if we are simplifying conflicts. That Rainham needs to move to bolster the Cannon X - Gravesend - X service back to a metro. It's fine to drop CX on a line if the frequency is good, in theory. LB was rebuilt to make changing better, and has been a success. Not to mention that Crossrail at Abbey Wood (and for Woolwich itself) give another link into the West End, so this change is perfectly acceptable now.
Cannon St is ostensibly Bank tube now too, with the new entrance (and Bank works!) so connectivity - even on a weekend, is not so shabby.
I've always liked the quirky peak Blackfriars services. Sidcup via Nunhead is def a curious one.
Finally, on Hayes - I do like the idea of weaning them off City service years in advance of a Bakerloo

- get it all west-end focused.
