I don't have an exhaustive list of the proposed definitions to hand.

But perhaps "[in London] run by TfL, but not LU" might qualify.

If you're using that to *disqualify* the GCR, then you're saying that EL
and LO are **the only mainline railways** which clearly isn't what was
intended by the words you've quoted (they would have been intended to
*include* EL/LO in the definition, not to *exclude* all others).

It's been posted upthread a few times.

Would that be the Leicester or Loughborough end that is [in London] by
your measure? I'm fairly sure TfL post-dates clusure (and also
re-opening) by a fair margin.

Try reading this thread. Here's an updated five possible definitions,
listed in descending order of restrictiveness:

1. Only public transport lines with 'Main Line' in their official names

2. Any NR routes with both fast and stopping trains

3. NR lines served by longer distance (eg, >30 miles) and not just
regional/local trains

4. All NR passenger lines, or connected lines maintained by NR (eg, HS1,
Heathrow)

5. Any standard gauge heavy rail public transport line run by or connected
to NR, other than LU.

> But perhaps "[in London] run by TfL, but not LU" might qualify.

How would that fit in?

Several lists have, but I don't think any claimed to be "exhaustive".

Neither, it was simply one of the non-exclusive definitions which might
have caused the award of a "mainline medal".

You are getting a bit confused here. The words I uttered were one of
many non-exclusive criteria which have been suggested as indicating that
a line should be awarded a "mainline medal".
