They are the N5 and N20 which cover the northern
branches of the Northern Line to Edgware and Barnet.

Wasn't one of those actually promoted as "Your Night Time Northern Line"
on special route branding once?

This branding was used for the N1 and N5: I don't why or when the N1 became
the N20.

It's the size of a county and it comes every two and a half minutes
