First time lurker, first time poster.

Just a bit furious as to why they won't extend the London Overground to Streatham- especially when no new track needs to be built. Crystal Palace to Clapham Junction would join up Balham, Wandsworth and Streatham Hill/Common and all would be well with the world.

Thoughts?

I think they are planning on making it circular at some point no?

Yes, its a pity it doesn't share stations with the central , piccadilly and
northern lines which it crosses. Then it may be genuinely useful to a lot
more people.

Sort of, depending upon your definition of circular - phase 2, due to open
in December 2012, will add a new branch to the East London Line from Surrey
Quays to Clapham Jn (via Queens Rd Peckham, Peckham Rye, Denmark Hill,
Clapham High St, Wandsworth Rd, then Clapham Jn). Trains won't actually run
through onto the West London Line though - pax will need to change trains at
Clapham Jn if they want to head to say Kensington Olympia (this change will
be v easy though).

There are I think various thoughts about further London Overground services
south of the river, specifically from Crystal Palace via Streatham to
Clapham Jn, but nothing's imminent on that front.

Clapham High Street to Clapham North (Northern line) is a pretty easy
interchange.

There are already 4 Southern trains an hour between Crystal Palace and

There was once a plan to link the East London Railway (as was) with
the Lea Valley Line somewhere between Bethnal Green and Cambridge
Heath.

Also it would have been nice if there were platforms reinstated on the
mainline (maybe Lea Valley tracks only) almost directly beneath
Shoreditch High Street, as the ELL has no interchange with the Central
line or with National Express.

I was thinking more of the NLL where it whizzes past a load of tube lines
without stopping. Obviously this isn't TfLs fault but I can't help wondering
why for example North Acton on the central line was built about 300 metres
away from where the NLL crosses it instead of building a station there.
But then it doesn't even interchange with the piccadilly line which also
crosses it which is Gold standard ****wittedness on the part of the original
builders of both lines.

Cleaner, bigger nicer trains- AFAIK you can't get a train from CP to Streatham Common either, a new bit of track would have to probably be built for that though, through the Streatham Hill train yard.

The circular route that is planned is a joke, as people mentioned, you need to change at Clapham Junction (the LO platform is a joke there too, covered in weeds, even after they closed it for 4 weeks for maintenance). You'll probably be dropped from Crystal Palace/Surrey Quays at Clapham on platform 17, leaving a 1-2 minutes walk to platform 2 for the LO interchange.

The lack of a Central Line interchange was intentional, it was decided early
on that an interchange with Crossrail at Whitechapel would be better for
distributing passengers more evenly.

Rivalry between competing private companies.

North Action was on the New North Main Line - a joint scheme of the
Great Central and Great Western to speed up their access from the
midlands to London.

The North London Line, on the other hand, was essentially under the
control of their great rivals - the LNWR and the Midland Railway.

That's definitely been mentioned, because they expect significantly altered

How is opening an extra station on one of the most crowded parts of the
network a good idea? They made passive provision for a Central Line
station, that was the right thing to do.

Yes , good point. And taking that further - Oxford Street is very crowded so
lets get rid of the central line interchange there and make everyone walk from

But they didn't close for maintenance of platform 1, the closure was for
double tracking of the approach tracks.

You definitely won't end up in P17 from the SLL, because there is no rail
connection. The SLL service will run into a new platform 2, which will be
the current platform 2 extended out by one track width over half its length,
at the Wandsworth end. The WLL will run from the existing platform face,
which will be renumbered as P1. I'd expect that resurfacing of the whole
platform, and reopening the second set of stairs, will be done once the work
actually starts at the station....

Handy diagram he

http://www.sucs.org/~cmckenna/diagra..._2a_and_2b.png

It describes the SLL platform as 2b and the WLL as 2a, but the latter
may well be renumbered as 1, as there is no hope of getting the original
platform 1 back in service.

The important thing is that there is easy and step-free interchange
between the two segments of the orbital route.

I think some are missing the (potential) bigger picture.

Extending the (outer SLL) Crystal Palace service to Clapham Junction
would use platforms 16 & 17, which could then be extended up the WLL
to Willesden Junction. The SLL service would then have platforms 2a &
2b all to itself. As has been mooted elsewhere, they could conceivably
then extend these to Wimbledon via East Putney if they rebuilt the
flyover at the very least...though they'd probably have to reinstate
platform 1 for that as well, depending on whether 2b is obtained by
building out the platform to make a bay or by dividing the platform
and using a crossover.

You can't just extend it to Streatham Hill/Common, because there's no
facilities for turning trains around - no bay platform, and not enough
capacity to let them tie up a through line for a few minutes without
seriously screwing up all the other routes. Instead of terminating at
Streatham Common, they'd have to go through Norbury and Thornton Heath
to Selhurst and then reverse in the depot, or go through to West Croydon
(but the bay platform is already in use there for other services) or to
East Croydon (which also already has trains being reversed there.
Similar for Streatham Hill.

Not to mention that those trains would have to cross several more
junctions, and share track with several more services, all of which
serves to make a service less reliable.

One has to wonder why that wasn't done at the same time as they laid the

to be closed *again* while those works are going on.

Does anyone know why not? I distinctly remember hearing Ken Livingstone in his day saying that the London Overground would provide London for the first time ever with a circular service through the suburbs. He quite obviously saw the London Overground as a kind of Outer Circle Line.

Currently we have services from New Cross etc terminating at Highbury And Islington while other services from Stratford go through Highbury And Islington to Clapham Junction. Why is this arrangement better than a straightforward Outer Circle system?

Because it provides terminating points where the service can recover
as well as provide isolation from disruptions on the other half.

Think about what happens on the inner Circle Line when a train breaks
down. Nothing can pass it, so services back up, and until you get to a
point where you can reverse trains, everything grinds to a halt.

In an ideal world, you'd perhaps have two semi-circular services
operating on the Circle instead: Something like Kings Cross to South
Kensington via Liverpool St., and Kings Cross to South Kensington via
Notting Hill Gate. Problem is that some will want to get from one half
to the other without changing. Notting Hill to Liverpool St is easy -
use the Central Line, but something like Paddington to Aldgate is a
bit more problematic. Have another pair of overlapping services
perhaps, maybe between Tower Hill & Paddington...but space for the
terminating platforms needed is hard to find, so the ideal locations
aren't always possible.

Well, that's why the Circle line is no longer circular: it's two
services that meet at Edgware Road. If you want to go from Bayswater to
Baker St, you have to change trains (unless you choose to go the much
longer wrong way round).

I expect because the works just done were part of the NLR improvement
project for the enhanced WLL frequency, and the work yet to be done is part
of the SLL project. A different type of money probably...

You may well be right but that's a very negative line of reasoning. First, how often do they have train break-downs? Second, why not have a contingency plan for that kind split system in the event of a train break-down but in normal circumstances operate a conventional circular service?

Incidentally if splitting the service to provide a safety margin is so advantageous, why not use the idea to incorporate some of the extensions to the London Overground that have been suggested in this forum over the past few months. For example, instead of the current Richmond to Stratford service, why not Richmond to Caledonian Road and Queens Park to Stratford?

Because Richmond to Stratford is already about as straightforward as it
gets, an end to end route for LO into dedicated terminal platforms, even
though it is overlaid with freight movements.

What you are suggesting would add at least three more areas of complexity;
reversing at Caledonian Rd, additional flat crossing conflicting movements
at Camden Rd West Jn, and reversing at Queens Park, where the existing
service already has to be pathed with the Bakerloo line.

Also, you'd presumably expect to have space for more trains along the
section where the two routes overlap - if not you'd have to reduce the
number of departures from Richmond and Stratford...

A break down is the most obvious case. The far more common one is
gradual accumulation of delay seconds. A held door, a delay of a Met
service beyond Baker St., A District service running late due to a
passenger alarm...all these things can cause the Circle service to
start running late. Without a terminus...it can only get later and
later, and eventually, the lateness builds up and it starts missing
it's path at junctions and controller intervention is needed to fix
things by taking something out of service, probably at Edgware Road as
it's one of the few locations with the correct trackwork.

It's why I'd like to have the former widened lines as part of the SSL
system. Assuming connections made at Farringdon and Moorgate, give the
centre roads over to the Circles, and run the Mets on the outer lines.
Circles could be scheduled to simply bypass delayed units on these
sections. A similar arrangement could be instituted between Gloucester
Road and South Kensington (where it already kinda does, as the
westbound District and Circle are kept separate). Knock though the
bays at Mansion House and Tower Hill and you have another couple of
locations where you can do this as well. Maybe Aldgate too ;)

It is known that connections can't be made at Moorgate without spending 100s
of millions though - the alterations to have a junction east of the
platforms involve adjacent building foundations - and there is basically no
way a business case would ever stand up.

By the time the SSR resignalling is complete in 2018, it is not intended to
have any Mansion House terminators, and the bay platform there is to be
taken over by the through route. However there is a plan to make Tower
Hill's central platform accessible from both directions...

Often enough for it to be worth thinking about.

They also get vandalised by feral passengers, or have to wait for ages
in a station because someone is ill, or get delayed by inconsiderate
suicides, or ...
Second, why not have a
contingency plan for that kind split system in the event of a train
break-down but in normal circumstances operate a conventional circular
service?


That might be practical if LO was the only operator using those tracks -
they could just have two timetables and flip between them at will. But
they're not in that lucky position, so the other operators would have to
also have two timetables. Imagine if LO wanted to change the timetable
between Clapham Junction and Willesden Junction. That means that
Southern have to change their timetable on that bit of track, which
means Southern also have to change their timetable both south and north
of it, which means that whoever it is they share track with to the north
also has to change timetables, and so on.

One has to wonder why that wasn't done at the same time as they laid
the extra track just north of the platform. Presumably platform 2 will
have to be closed *again* while those works are going on.


Well, it looks like that work started over the weekend, with trains now
stopping further along the platform where there are some new buffers
installed. The southern half of the platform is now hidden behind
wooden hoardings.

Platform 2 is still open, but because of the hoardings and the pointless
unused buildings that are still standing in the middle of it, is even
narrower than normal and even more crowded when southbound trains empty.

No evidence of re-surfacing the northern end of the platform.

I know...but it's still unfortunate. Interestingly, these foundations
don't seem to be a problem for Crossrail...

It's such a shame...as once you get past those foundations you have a
clear run for four tracks across Finsbury Circus to Liverpool St. East
of there...well. I don't think you'll even be able to widen the former
bay for an extra platform, let alone have a junction east of
there...but I guess if you could redevelop the building sitting over
where that needs to happen it could...

By the time the SSR resignalling is complete in 2018, it is not intended to
have any Mansion House terminators, and the bay platform there is to be
taken over by the through route. * However there is a plan to make Tower
Hill's central platform accessible from both directions...


Quite. However, rather than projecting Mansion House's centre bay to
the eastbound line and severing the western connection to the
westbound, how about projecting it to the westbound and retaining
it's western layout (turning it into a westbound loop). Knock through
the disused northern bay and connect it at both ends to the eastbound
line, and hey presto, you have a pair of island platforms where
services can be reformed. Having a shared bidirectional centre loop is
easier and cheaper...but not as flexible by a long shot.

....I suspect a shared centre road is the plan at Tower Hill, but
likewise, I think a pair of loops (a-la the old Whitechapel - I really
wish they'd found a solution that kept the centre roads) would be
*much* more useful.

Does anyone know why not? I distinctly remember hearing Ken Livingstone
in his day saying that the London Overground would provide London for
the first time ever with a circular service through the suburbs. He
quite obviously saw the London Overground as a kind of Outer Circle
Line.

Currently we have services from New Cross etc terminating at Highbury
And Islington while other services from Stratford go through Highbury
And Islington to Clapham Junction. Why is this arrangement better than a
straightforward Outer Circle system?

Practicality and customer demand. Joining the SLL and WLL would mean
missing Clapham Junction, a major traffic objective. Westwards from
Highbury to join ELL and NLL is possible (current track arrangements
notwithstanding), but would be an operational nightmare given 7½
minute services on each and a lot of freight on the latter. And the
major traffic objective for the ELL is Highbury & Islington with its
Victoria Line and GN Electrics connections.

All the lines are shared with other services, some of which permeate
far into the Home Counties and bring all their operational baggage
with them. You really don't want to perpetuate all the accumulated
delays in a circular service. Circular itineraries propagate any
problems indefinitely around the service, which is why even the Circle
Line has been de-circlified.

The projected service pattern is the best one to fit travel patterns
and operational practicalities. Onward connections at Clapham
Junction will be as easy as possible – just shuffle down the
platform. At Highbury, either cross-platform or over a short bridge.

It's sufficiently 'underground' presumably.

Yes, but the point is that the greater depth allows a wider choice of
route. You still have to avoid the foundations, because many of them
are piles that were bored upwards of 30m deep, starting from a deep
basement. Also, it's not about avoiding physically hitting the piles
themselves, but about avoiding where they put their loads into the
soil below. ;-)

....and by Crossrail, I also meant the passenger walkway tunnels et al,
which are very close to the surface (and will block anything like this
quite comprehensively).
