Line maps and announcements are beginning to mention interchange with
London Overground services. This is already a little confusing -
Euston, Highbury and Blackhorse Road all interchange with entirely
different lines, though you wouldn't know it from the linear map of
the Victoria line.

And if Ken is serious about bringing more and more lines into the LO
branding, the situation's going to get worse.

So... would it make more sense to give individual routes names? Or
even numbers, continental style? If so, what could they be?
