Central line
 

The Central Line is a line of the London Underground and coloured red on the
tube map. It is the second busiest line on the Underground after the
Northern with 183,512,000 passengers per annum. It is a 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?

Thanks.

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 was added by an anonymous user last August, so it's probably
********. West Ruislip-Epping is definitely the longest end-to-end
journey, because no other line goes so far out at both ends. Add on
the Hainault Loop (2/3rds the length of the entire Victoria Line), and
nothing can touch it route mileage wise either.

So it's the longest by any metric.

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!

Only in the sense that it's infinite ... but otherwise very short.

Aha, I've found a reference (dated 1987)

Circle, Hammersmith and Metropolitan 51 (of which the Circle is
13)

East London 4

District 40

Northern 36

Central 52

Bakerloo 14

Also, it would be better to say "with 183,512,000 passenger journeys
per annum". The wording used seems to imply that the number of people
who use the line at least once in a year is approximately three times
the entire population of the UK!

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?

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.

The 'line' names designated by LUL are not indicative

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.

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.

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

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?

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).

If you're allowed to cover the same route twice (just not the same

It starts to the north west of london , loops around central london

Yes of course, I did not think of the possibility to avoid returning to
the Chesham single-track line by terminating in Amersham instead. Good
