I did not penetrate documents as far as finding proposed service

might be helpful - it was probably there when that service was an
isolated Northern Line service before the 1975 disaster.

considerations apply to Farringdon - Blackfriars.

Not probably but actually. The Northern City line was part of the
Underground before 1975 so was of course on the map. It continued on it
for some time after the transfer to the GN.

At least 20 years looking at this website of tube maps through the years.

The Northern City would seem to have vanished from the map around the
turn of the century.

Sounds about right. Didn't Thameslink in central London go at the same time?
