Leaving out the Moorgate to FP section of GN - even if they don't
include
the rest - is just cretinous and a disservice to passengers.

I'm not sure why it's worse than leaving out the Waterloo-Wimbledon
(etc) National Rail routes.
I'm not sure where one should draw the line (pun *not* intended!)
between which lines to include and which to omit.

[..]

I suppose the criterion for inclusion might be whether a typical
ticket for use on the Underground would or wouldn't allow you to use
a non-Underground line that called at stations within the zones that
your ticket covers.
As a London tourist, I would have drawn the line at a service frequency
as well: There should be a minimum of 6 tph (maximum 10 minutes waiting
time) during daytime for the line to serve a meaningful purpose as a
local connection.

Would you exclude TfL Tube [subsurface] lines which didn't comply with
that frequency?
