The Central Line is a line of the London Underground and

deep-level "tube"
line, running east-west across London, and has the greatest
total length
of
track on the Underground (but is not the longest continuous
line)

Just read the above on Wikipedia....what is the longest
continuous line
it
is referring to?

It's a strange imprecise term to use. In fact, the whole thing
is
really, because "lines" are not really all that separate.

It also seems to be the wrong way round. The Central Line is
longest
end to end (Epping to West Ruislip), but I would have thought
other
lines had more track mileage.


It seems to imply there is another line

"(but is not the longest continuous line)"

The only other concept of "continuous" anything on the Underground
that
I am aware of is the longest continuous section of travel in
tunnel.
That is on the Northern Line from the portal at East Finchley via
the
Bank Branch to the southern portal just at Morden station. I can't
think of any other relevant comparison but if people will use
imprecise
terminology for something as complex as the LU network!


Cockfosters to Cockfosters via Heathrow?


Just thought about that too (and Kennington loop)... Would
Cockfosters-Heathrow-Cockfosters be the longest a train will go on the
system without reversing? Or would a Circle Line train travel longer
before it becomes something else than a Circle Line train and going out
somewhere and reversing?

Quite.

I just took the parenthetical remark out, with an edit summary of
"What? West Ruislip to Epping is the longest single journey on LUL by
track mileage."

I'm sure Epping to West Ruislip must be slightly longer ...

Which line is longer in the Shepherds Bush area?

I suppose the longest journey that is theoretically possible would be
Chesham to Upminster, not including the circle line.

Assuming no reversals or repetition of any stretch of route, I'll
venture Chesham to Uxbridge (via Baker Street, Liverpool Street, Tower
Hill, and Ealing Common) as being longer.

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.

I'd think not much in it. They each seem to take two sides of a
parallelogram with Shepherds Bush and White City at opposite corners.

The 'line' names designated by LUL are not indicative

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