How much geographical information do the names of the Underground lines convey?
- Bakerloo - when you know it connects Baker Street and Waterloo, I guess that is some help, but it isn't even the only line that does that.
- Central - all the lines serve Central London.
- Circle - is kind of a circle, apart from the bit that isn't, but that's fair enough.
- District - meaningless, London is full of districts
- Hammersmith & City - woo-hoo, this one does what it says on the tin - apart from the eastern leg.
- Jubilee - no geographical connection at all
- Metropolitan - meaningless, all of London is the metropolis
- Northern - serves the most southerly station on the network
- Piccadilly - goes through Piccadilly Circus, but it isn't the only line to do that, and it does go a long way north and west as well
- Victoria - goes through Victoria, but it isn't the only line to do that, and it does go a long way north and south as well
- Waterloo & City - at last, we've got one where the name does tell you where it goes
There are one or two of the Overground lines where I think they've made a poor choice, but I also realise that my opinion is just that, my personal opinion, and I don't expect TfL to pander to my views.
Signage within the station always refers to "Northern Line", "Central Line" etc.
