Just a passer-by curious Hong-Konger's words:

I am always curious about why there's no lines like "Hyper Outer Circle"
nowadays. Maybe linking up Finchley, Hendon, Neasden and reaching
Willesden may be a funny idea after all.


Are you suggesting something like the Circle Line in Zones 3 and 4?

Even though such a line would be completely impossible to do, I could
see it running in a complete circle around London, starting at
Richmond and passing through Wimbledon, Vauxhall, Surrey Quays,
Mudchute, Canning Town, Barking, Leytonstone, Walthamstow Central,
Wood Green, East Finchley, Brent Cross, Wembley Park, South Kenton,
Alperton, and Hounslow Central, and eventually returning to Richmond.

But it would be almost impossible to do.


Not at all... once the ELL extensions are complete (that is, of course,
if they ever get started properly) then there will be an extremely easy
route available via Canada Water, Hoxton, Highbury, Camden Road, West
Hampstead, Willesden Jcn, Olympia, Clapham Jcn, Clapham High St, Queens
Rd Peckham and back to Canada Water. There is a reverse at Clapham Junction.

I doubt they'll ever actually run it as a full circle though. The ELLE
service pattern already includes Clapham Jcn - Canada Water - Highbury.
(I think the ELLE along with the NLL, WLL and Goblin are all meant to be
combined into one Orbirail franchise in the future).


Wow, interesting. It would be a great way to avoid Zone 1 during the
rush hour, and it would be a godsend if the Olympics ever came to
London.

In fact the powers that be believe that the Jubilee line will not be
able to cope during the Olympics if the ELL extensions are not completed.


Once the East London line is connected to the old North London NR
route, and services are running between Highbury & Islington thru
Whitechapel to Canada Water and beyond, how much longer would it take
for a Hyper Circle Line to appear?

Once the ELL extensions are complete, the main obstacles to a full
orbital service are to do with train pathing, i.e. trying to find room
to fit orbital services between the passenger trains and large number of
freight trains using both the NLL between Willesden and Highbury, and
the WLL between Willesden and Clapham. Both these lines would require
signalling upgrades and possibly extra tracks (although according to the
Olympic bid, the current 4 trains per hour on the NLL will be increased
to 10 tph, which must require these improvements anyway!)
