The Advent Circle [C-1] (a 12 day countdown to the de-circling of the Circle line) Even though it's never been a perfect circle, and from tomorrow won't even join up properly, the Circle line is still to be called the Circle line. It would cost too much to change the name everywhere in every reference at every station everywhere on the network. Better names for the nu-Circle line include the Spiral, the Lasso, the Tadpole, the T-Cup or the Paperclip. But they're not better names, are they, not really? There's a far better name the new Circle could have, except it's already been taken by another line... The Hammersmith and City line earns its name because it starts at Hammersmith and passes through Barbican, Moorgate and Liverpool Street stations, which are within the boundaries of the City of London. But from tomorrow there'll be two lines that start at Hammersmith and pass through the City. And the new Circle line passes through Barbican, Moorgate, Liverpool Street, Tower Hill, Monument, Cannon Street, Mansion House and Blackfriars, making it even more of an "& City" line than the official H&C. But there's no accounting for logic, so we'll all have to stick with a Circle line that isn't circular, and a Hammersmith and City line that doesn't serve much of the City. From tomorrow. Take your final ride on the circular-ish Circle today.
