I never even mentioned Trafalgar Square or the AA the only location I
mentioned was the original Charing Cross

The original Charing Cross was located at what's now one of the corners
of Trafalgar Square.

and even then asked for other opinions on that rather saying it must
be so.

My opinion, based on quite a lot of research, being: having earlier
specified mileages to various gateways like Marble Arch, the AA decided
for its maps to consolidate on Trafalgar Square. This has become a meme
about "Charing Cross" (the original one only having a plaque) and an
unspoken implication that it has always been the case (long before the
AA)

Its almost as if you are wanting me to argue that your suggestion was wrong
so you you can start one of your long winded arguments to bolster your
ego even though I haven’t actually disagreed with you, just not accepted
that the one you put forward has any more merit

Only precedence over Turnpikes and Trafalgar Square, and I wouldn't
accuse you of ego over the mention of Ongar for the tube distances, so
I'm not sure why that comes into it. I'm trying to write about some
serious historical research here.

My mention of Ongar was done because it is an interesting Railway factoid
and also an example to our Aberdeen correspondent that the London Transport
they remember as an example tradition of the good old days initiated a
major Metrication exercise 40 years ago, it was from that you seem to have
decided that you want to hold a point scoring debate ,an activity you are
renowned for by mentioning the Post office datum which turns not to be the
only candidate

It's the original one, though (if you ignore the Romans). And the
Turnpikes used a range of gateways (not unlike the AA did originally,
perhaps they modelled themselves on those).

for distances too and from London .

At least the Ongar one can be verified

The Post Office one can be as well. The mystery about the Charing
Cross/AA one is that as far as I can tell no-one has ever been able to
expand on what it says on that fairly recent and vague plaque.

I think I'll do a FOI on Westminster City Council, and see what they
have to say.
