I was thinking about how much of the London Underground map (including Overground and DLR) I've covered over the years. This is what I've done so far. Bakerloo: Warwick Avenue to the Elephant. Central: Shepherd's Bush to Debden (excluding the Hainault loop which I haven't touched so far) Circle: All of it. District: Tower Hill to Wimbledon, and up to Edgware Road. Hammersmith and City: Hammersmith to Mile End. Jubilee: Baker Street to Stratford. Metropolitan: Aldgate to Baker Street Northern: The entire Bank branch, and the Charing Cross branch up to Waterloo. Haven't been further north than Camden Town. Piccadilly: Finsbury Park to Earls Court Victoria: Vauxhall to Walthamstow Central Waterloo and City: All of it. I also did the old East London line back in August 2007, from Whitechapel to Canada Water. Quaint little line back then. I wish I'd been older to have had more trips on it before the upgrade, but hey ho. Overground: East London line from Canada Water to Dalston Junction. North London line from Caledonian Road and Barnsbury, to Willesden Junction. DLR: The entire original Stratford branch, Bank to Greenwich, and Poplar to Cusom House. On Saturday, I have plans to go up to Archway on the Northern. After catching the number 41 bus to Turnpike Lane, I should clear a little bit more of the Piccadilly. And I intend to finally clear Tower Gateway, which I should have done back in February 2008. Got there on the day, and found out that the service had been suspended due to signal failure. Apologies if this is in the wrong section of the forum.
