Just saw this via the London Reconnections blog and, oh my god, I think you could not do a worse job of redesigning the tube map if you tried.
“Paint all the lines the same colour. Send a train into London centre from Zone 6. Which identically coloured line does it emerge from on the other side? Fuck knows. Good luck!”
I mean, look at Oxford Circus? Which are the through lines? No? Me neither.
And this is promoted as “accessible”. God help us all.
