No-one seems to have mentioned that the Victoria Line is kind of a

Goblin if it had decent interchanges, or used to be done with the "Goblin"
when it ran to St Pancras, are done with the Vic instead. That's not much
use if you live in Crouch Hill or Harringay though.

It may be true for the Walthamstow half of things, but the Vic is pretty
useless east of there!
