Surley these routes do not count because they involve changing lines?

The 'line' names designated by LUL are not indicative
of whether the actual tracks are (or are not) connected.

But the original question was about the longest 'line', so this is in fact
germane.

But this wasn't an attempt to answer the original question. It was a
digression onto the subject of what might be the longest journey
theoretically possible.

Furthermore, LU occasionally changes the definition of a 'Line', so some
of the fantasy journeys invented in this thread could, in theory, become
possible on a single future line. For example, some of today's
Piccadilly Line was originally part of the (Metropolitan) District Line,
and the Circle + Hammersmith & City lines are due for a shakeup in a few
years time.

Indeed, Amersham to Barking could be a regular reality when the
service patterns change...

Chesham to Upminster is the longest trip a train could physically take
without reversing or going in circles AFAIK.

True, but rather less likely to happen.

As somebody already suggested, Chesham - Aldgate - Tower Hill - Ealing
Common - Uxbridge is much further.

Thats effectively going in a circle. Chesham and Upminster are the
furthest apart you could go in a single trip (and possibly the
furthest stations apart full stop).

Are there crossovers that allow you to change lines at Mile End? If so,
could you, given the right sort of train, do Chesham - Aldgate East - Mile
End - Leytonstone - round the loop - Leytonstone - Aldgate East - Tower
Hill - Ealing Common - Uxbridge? Or does the Aldgate East to Leytonstone
bit make it count as a circular route?

Thats effectively going in a circle.

Boltar, have you ever seen a circle? If so, would you care to explain the
resemblance of the above route to one?

This was evidently not made clear to the OP!

If you count such circular routes we can take for example Upminster -
Earl's Court - over to Piccadilly Line tracks - round the Heathrow loop
- back to District tracks - Earl's Court - Aldgate - Chesham. This can
as far as I can see be done without going over the same track twice or
crossing it's own route (if it is done in this direction, it will cross
tracks already used if it is being done in the opposit direction).
