London Overground
 

Last Wednesday, I was in London for the day. After enjoying Southwest
Trains and London Underground, I experienced London Overground for the
First time. An aside: I was surprised by the way delays on the
Underground were announced as they are a normal occurrence.

Having utilized the Northern City I joined the Overground (North
London Line) at Highbury & Islington. The East London line side was a
hive of activity with numerous orange jacketed workers in
attendance.

Highbury & Islington station looked as if it has been largely
rebuilt. It is a very different place from the H&I of the early
1970s. The new platforms and footbridge look very good.

Onwards, I travelled to Kentish Town West. It is disappointing to see
the route narrow to two tracks. Would that the ELL could extend to
Camden Road. The bridge at Camden Road is a sad sight.

Considering the length of many journeys on the Overground, the new
trains seem well designed for their purpose. They are functional and
spacious with helpful PIS systems. They are certainly a change from
the LMR slam door stock I recall.

Generally the Overground is taking on a TfL atmosphere. The
improvements are numerous, with staff in evidence and wider entrances
and lobbies. Gone are the days of the unstaffed stations with tiny
turnstiles.

Well done TfL.

Yes, agreed, though I think they could have included a bit more padding
on the seats, plus more internal route maps, visible from all seats, as
in most Tube trains.

It'd also be cool if they would start offering service on the NLL from
Camden Town at least to Queen's Park. But I guess that's more of a dream.

Did I hear at some point, however, that they may eventually extend ELL
out to Canden town?

That would be great. Better yet extend the ELL to Queens Park, or
Watford. That would mean dual electrification thru Primrose Hill.

AIUI there was dual electrification between Primrose Hill and Camden Road
from the time the short-lived Maiden Lane freightliner depot was opened
until quite recently - but has the third rail now been removed, as the NLL
is now OHLE only from Stratford to Acton. ELL units which use the connection
west of Highbury & Islington will have to change to 25 kV OHLE.

There were a while ago suggestions of restoring a Camden Road - Primrose
Hill - Queens Park service, though in the unlikely event of this coming
about it seems more likely to be operated by trains from Stratford rather
than the ELL.

It's unlikely that we'll ever see any more dual electrified lines.

No it wouldn't, it would mean fitting the transformers into the space
left for them on the 20 DC only class 378s (or just running the
service with some of the already dual voltage class 378/2 units as not
all the ELL trains are DC only. If need be the Euston - Watford
Junction service could be run with some of the class 378/1 DC only
units to release more dual voltage units).

Don't think it has ever been proposed officially. The track layout is not
designed to allow for extending the ELL west of Highbury & Islington anyway.
Between there and Camden Rd it is laid out as a two track railway in the
centre of the formation with long passing loops for freight on the outside.
Before the works were slightly reduced, there was a plan for a third
platform at Camden Rd, but this was to allow a Stratford - Camden Rd shuttle
to run.

There are two main reasons it won't happen, IMHO. Firstly, the NLL capacity
is only 8 tph in the peak, and 6 tph offpeak, to allow for the freight
traffic, so there is no room for additional trains from the ELL without
reducing the NLL service. If paths were available, eastbound trains towards
the ELL would have to cross westbound passenger and freight trains trains
from the Stratford direction, this would not allow a robust timetable.

Hasn't this extra platform at Camden Road just been postponed. DfT and
TfL were fighting over who was going to pay for the bridge
refurbishment work needed on the northern side of the formation at
Camden Road. So the extension of the four tracks beyond the station
won't now happen until after the Olympics (of course there may have
been another change of plans which I missed).

It's also unlikely to happen due to the layout at Highbury and

changeover would also be needed.

The bridge refurbishment and reinstatement of tracks was a freight only

deathly hush for many months and I'd not be surprised if it has been
gently pushed off the DfT / Network Rail shopping list. I've not read
or heard anything about it anywhere for a long, long time.

I understand (from other forums) that the shuttle service is no more and
what LOROL will do in the peaks is run 4 tph Stratford - Clapham
Junction rather than the planned 2 tph. There is no fleet impact [1]
plus there is a better service Camden Road - Willesden Junction.

But that would mean 8 tph between Camden Road and Willesden Junction. I
thought the reason why it was limited to 6 tph was in order to allow for
freight paths. Otherwise, why plan for two shuttle services
(Strat-Camden and WJ-CJ) with all the operational complexity?

But any third platform at Camden Road would need part of the northern
trackbed (and at least part of the western most bridge) refurbished,
otherwise there would be no access to the platform face on the other
side of the current eastbound platform.

It would only be 8tph during peak periods, when freight access is
limited (due to lack of capacity over the Camden Road - Primrose Hill
route to the WCML, if nothing else).

The freight loops are a problem. If they could be moved elsewhere, it
should be possible for the ELL to utliize the southern pair to Camden
Road and Primrose hill. Freight and the NLL would run on the northern
pair. It would mean new signalling, a reinstated bridge, and new
platforms.

It would also need a piece of new bridge/viaduct (over Kentish Town
Road) at the western end of Camden Road, between the station and the
junction. Otherwise all the trains will still be sharing a short piece
of double track where the junction is.

Yes - however, as others have pointed out, it has all gone a bit quiet on
that possibility.

It's also unlikely to happen due to the layout at Highbury and
Islington, with only a single connecting track on which a voltage
changeover would also be needed.

Agree - I probably oversimplified that point when I wrote "The track layout

Yes, agreed, though I think they could have included a bit more padding
on the seats, plus more internal route maps, visible from all seats, as
in most Tube trains.

Agreed also! Although I think any maps should just show the specific
"service group" for the train, i.e. only those services running West
from Stratford, or only those running East from Highbury and
Islington. The map that shows the entire Overground is too all
encompassing, and geographically challenged.

Yes, that would be better, though I'm not sure that the dual voltage

The trains aren't limited to particular service groups though.

All the dual voltage units can and do show up anywhere, NLL, WLL, DC and
ELL. It is only the DC units that are constrained to the ELL, (and the SLL
extension when it opens - and makes the map even more 'challenged').

Not quite fulfilling your wish list but during the upcoming blockade
in late February the NLL trains run Stratford - Watford Junction via
Primrose Hill. You can dig out details of trains on the NR website -
the service seems to be every 20 mins or so.

So it'll be possible to catch a direct train from the 2012 Olympics site
to the sites of both the 1948 *and* 1908 Olympics (via both the Central
Line and Overground when it's running).

Of course, the 1908 Olympics site already has regular connections to
both the 1948 and 2012 Olympic sites, so for that brief period, all
three Olympic sites will have direct rail links. This certainly wouldn't
be possible anywhere else in the world, and not often even in London.

And you can do it all on an Oyster card, too. Maybe people will be
attempting Olympic triangle records, with Oyster recording the times?

platform at Camden Rd, but this was to allow a Stratford - Camden Rd shuttle
to run.

There are two main reasons it won't happen, IMHO. *Firstly, the NLL capacity
is only 8 tph in the peak, and 6 tph offpeak, to allow for the freight
traffic, so there is no room for additional trains from the ELL without
reducing the NLL service. *If paths were available, eastbound trains towards
the ELL would have to cross westbound passenger and freight trains trains
from the Stratford direction, this would not allow a robust timetable..

The freight loops are a problem. *If they could be moved elsewhere, it
should be possible for the ELL to utliize the southern pair to Camden
Road and Primrose hill. *Freight and the NLL would run on the northern
pair. *It would mean new signalling, a reinstated bridge, and new
platforms.

It would also need a piece of new bridge/viaduct (over Kentish Town
Road) at the western end of Camden Road, between the station and the
junction. Otherwise all the trains will still be sharing a short piece
of double track where the junction is.

I've proposed this several times, as it seems quite a no-brainer to me
to give a totally segregated DC metro service from Watford Junction to
Surrey Quays and the branches following it. If more of the freight
could be diverted via the Goblin and Hampstead Heath (or better yet,
via some other route bypassing inner London), then the issue of the
fright loops becomes moot. The LO lines are no different to the SSL
lines, and we all know what capacities are possible on those.

However, this will become impossible thanks to the strange choice of
method chosen to link HS2 to HS1. They are proposing to tunnel a
single-track tunnel from Old Oak Common all the way to Primrose Hill,
then rise up and take over one of the tracks (widened to UIC gauge)
onward to St. Pancras. I suspect the widening required might require
the removal of the other track over the viaducts though. Why they
don't just continue the tunnel a few hundred metres more to St.
Pancras is beyond me. Sure it will save a tiny fraction of the cost,
but you're crippling the LO network's future prospects.

Freight from the GEML can't realistically use Goblin, which in any event
will be heavily used from Ripple Lane and the new port at Thames Haven, and
potentially from HS1 via the Rainham freight link. The freight via Goblin is
likely to need all available paths via Hampstead Heath, though there is a
need for freight from the GEML bound for the GWML, the SWML, or the WLL to
run via Camden Road and Hampstead Heath. This means that freight from the
GEML to Willesden or the WCML has to run via Primrose Hill. Then your
segregation of the ELLX to run via Primrose Hill, and the NLL via Camden
Road and Hampstead Heath will be compromised by freight crossing between the
two lines Between Highbury and Camden Road, or at Camden Road.

If a passenger service is to be reinstated over the Primrose Hill link, a
much better arrangement would be for the ELLX to continue to terminate at
Highbury & Islington or Dalston Junction, with NLL services running
Stratford to Richmond via Hampstead Heath, and Stratford to the DC lines via
Primrose Hill. Electrification of Goblin and alterations at Gospel Oak might
also allow a Barking to Clapham Junction service.

I have to ask where the demand is for such a long service? Would people
really travel on a DC stopping service via East London from Watford to
South London? Surely the imperative is to boost WLL capacity and add a

I also cannot see hundreds of millions of pounds being spent to change
an alignment on which hundreds of millions have just been spent to
provide sufficient capacity for Overground and freight services over the
NLL.

While there does seem to be a level of demand for a service via Primrose
Hill does it really need to be hugely frequent? Could not a x30 shuttle
from Willesden Junction to Camden Road not suffice? OK people will need
to change but there will be frequent services at both points to allow
that to happen. I may be a tad out of date about platform / turnback
provision at Willesden Low Level and Camden Road (3rd platform) so my
idea might not work.

If more of the freight
could be diverted via the Goblin and Hampstead Heath (or better yet,

And what happens to the GOBLIN service level if yet more freight has to
be pumped along that line? It might be possible to raise line speed a
bit and possibly squash some more signalling capacity out. Network Rail
opted not to fix the decaying bridges, that result in permanent speed
restrictions, during the recent upgrade works so where will the funding
come from to fix them? TfL and the DfT cannot or won't find £250k to
progress design work for electrification so I doubt we will see any more
money being spent on the GOBLIN for a long time - more's the pity as
it's a local line for me.

I also think we need some brave thinking about local North / East London
services linking down to Stratford via Lea Bridge. Again partly local
self interest but a service from Chingford via Low Hall curve and from
Enfield via South Tottenham to Stratford would generate patronage and
aid local mobility. The Enfield proposal would create a potential
capacity problem at South Tottenham given conflicting moves so that
would need some thought.

Heck you can run it with light rail vehicles for all I care - please
just provide the services. They could sensibly be run and marketed as
part of London Overground.

The LO lines are no different to the SSL

Well the SSL lines don't have to cope with freight. They also have far
higher demand levels than the Overground and have trains that are twice
as long. There are other remedies like longer trains on parts of the
Overground that will raise capacity before you start resignalling and
track realignment. Didn't Ian Brown have a vision of 5 car trains on
the NLL, WLL and DCs? Not sure about ELL but that is scheduled to have
16 tph on the core section when the new SLL opens in late 2012. I think
it will take a long time to exhaust the capacity of 16 tph on the ELL
although the southern branches may be fuller south of NXG.

I agree with you, I don't see end-to-end journeys as the target,
precisely for the reasons you state. The LO service use in my
experience is primarily a local one. Passengers travel for ~6 stations
or so at most before interchanging, be it to buses or other rail
services. Case in point, short of disruption, no-one north of Harrow &
Wealdstone takes the LO to Euston outside of disruption. Operating it
as a simple end-to-end service with reversal points would be just an
operational convenience to minimise performance pollution. Arbitrary
services could be Watford Junction-New Cross, Harrow & Wealdstone-
Crystal Palace, Willesden Junction-West Croydon and Dalston Junction-
Clapham Junction (which gives the core as Willesden Junction to Surrey
Quays).

I also cannot see hundreds of millions of pounds being spent to change
an alignment on which hundreds of millions have just been spent to
provide sufficient capacity for Overground and freight services over the
NLL.

Well, yes. That said, the infrastructure would hardly be wasted
though, would it? You'd be plain-lining the points at H&I and largely
finishing the works through Camden Road they planned to do anyway. A
higher service frequency needs more intensive signalling so perhaps
that would need looking at again. I'm not sure what the limits are on
the new stuff they've just put in. The only real new major
infrastructure required would be for 20m or so of the bridge widening
west of Camden Road, and I can't see that costing more than a few
million quid at worst.

While there does seem to be a level of demand for a service via Primrose

It would probably work were the turnbacks to be added, yes. The
ambition is to ditch the LO service into Euston though, so you need
somewhere for that to go. A turnback at Camden Road could probably
handle the 3tph fine, but ideally you want to be increasing service
levels beyond that. Look at the usage the Watford branch of the Met
gets versus the LO service and you'll see that market is there (though
admittedly the Met has the advantage of being faster past HotH, whilst
the LO would require the change at H&W for the same). People round my
way (Watford) mostly don't use the LO for spontaneous trips because
it's a 20 minute wait. Drop that to 10 or (at worst, 15 minutes), and
you have a different usage mentality.

And what happens to the GOBLIN service level if yet more freight has to
be pumped along that line? *It might be possible to raise line speed a

No they don't, and neither would a segregated DC line from WJ to
Surrey Quays if you came up with something from the City loop at
Willesden to Wembley Yard. It somewhat shifts the pressure onto the
NLL, but with the ELL covering the heavy section between Camden and
Dalston at increased frequencies, it should cope. Hell, be brave and
consider running the NLL fast through that section to increase
capacity if need be; change at Camden Road, Highbury or Dalston (OSI)
for the ELL. Probably unpopular, but gives a bit more of a point to
running two parallel services from non-adjacent platforms.

*They also have far
higher demand levels than the Overground and have trains that are twice
as long.

They do indeed. I'm not proposing 32 8-car tph ;)

There are other remedies like longer trains on parts of the
Overground that will raise capacity before you start resignalling and
track realignment. *Didn't Ian Brown have a vision of 5 car trains on
the NLL, WLL and DCs?

Increased frequencies need to come before longer trains. Get
passengers used to the tube-like mentality that you can wait for the
next one if this one is too full. That's not going to happen when the
next one is 20 minutes away.

If you increase the length of trains, you need to resignal things.
Overlaps change, point clearances, etc. all need looking into. Unless
the current work was done with that in mind, (tell me it was....) more
work will be required. I heard the 5-car thing as well, but haven't
seen anything I can recall right now first hand.

Not sure about ELL but that is scheduled to have
16 tph on the core section when the new SLL opens in late 2012. I think
it will take a long time to exhaust the capacity of 16 tph on the ELL
although the southern branches may be fuller south of NXG.

Indeed. It's a lot of capacity, and my initial proposal is to extend
half the terminating trains from Dalston to Willesden, half the H&I
terminators to Harrow, and the rest to Watford. That gives your 15-
minute frequency from Watford to Harrow, and removes the need for the
Bakerloo to Harrow as you will have 8tph between there and Willesden
Junction.

However, this will become impossible thanks to the strange choice of
method chosen to link HS2 to HS1. They are proposing to tunnel a
single-track tunnel from Old Oak Common all the way to Primrose Hill,

I think you need to define what you the LO network's future prospects
are before you can conclude that a HS2 link tunnel will cripple them.

I define the prospects as taking advantage of the Primrose Hill link,
which connects two parts of the LO network on either end. Severing
that link and removing the service to Euston (replacing north of
Queens Park with the Bakerloo) means closing Kilburn High Street and
South Hampstead. A simple, linear LO line from Watford to West Croydon
with short terminal branches to New Cross and Crystal Palace is very
simple for passengers to understand. Primrose Hill also offers a
opportunity to build an interchange with Chalk Farm, improving usage
on that section of line, and saving a good few pointless trips through
Euston for those wanting Camden.

As I say, I see the LO as SSL lines, just without the tunnelled core
sections, and I think they should be treated as such.

But the track arrangement would also need to be altered between

You also need to consider the freight connections from the East Coast
mainline. At the moment freight can't access GOBLIN from the ECML
without undertaking a double shunt (going the other way is OK),
however access via Camden Road is comparatively easy and only overlaps
with the NLL through Camden Road station itself.

*They also have far
higher demand levels than the Overground and have trains that are twice
as long.

Well about 40% longer as an 8 car S-stock train is 133m, whilst a 4
car class 378 is 80 meters (and the potential five car class 378 would
be 100m or 75% of the length).


They do indeed. I'm not proposing 32 8-car tph ;)

(the platform extensions etc. are long enough for example).

The Bakerloo might struggle to reverse all its service at Queens Park
as only the central roads of the north shed can be used for reversals
(the two through tracks don't have access to the other platform).
Harrow does have the advantage that it has a central reversing siding,
which is not present at Stonebridge Park (where some of the Bakerloo
trains reverse at the moment).

However, this will become impossible thanks to the strange choice of

consider running the NLL fast through that section to increase
capacity if need be; change at Camden Road, Highbury or Dalston (OSI)
for the ELL. Probably unpopular, but gives a bit more of a point to
running two parallel services from non-adjacent platforms.


You also need to consider the freight connections from the East Coast
mainline. At the moment freight can't access GOBLIN from the ECML
without undertaking a double shunt (going the other way is OK),
however access via Camden Road is comparatively easy and only overlaps
with the NLL through Camden Road station itself.

They also have far
higher demand levels than the Overground and have trains that are twice
as long.

Well about 40% longer as an 8 car S-stock train is 133m, whilst a 4
car class 378 is 80 meters (and the potential five car class 378 would
be 100m or 75% of the length).


They do indeed. I'm not proposing 32 8-car tph ;)

There are other remedies like longer trains on parts of the
Overground that will raise capacity before you start resignalling and
track realignment. Didn't Ian Brown have a vision of 5 car trains on
the NLL, WLL and DCs?

Increased frequencies need to come before longer trains. Get
passengers used to the tube-like mentality that you can wait for the
next one if this one is too full. That's not going to happen when the
next one is 20 minutes away.


I agree that increased frequencies are a good idea.

If you increase the length of trains, you need to resignal things.
Overlaps change, point clearances, etc. all need looking into. Unless
the current work was done with that in mind, (tell me it was....) more
work will be required. I heard the 5-car thing as well, but haven't
seen anything I can recall right now first hand.


But you'd also need to resignal to increase the frequencies. Much of
the recent work done has included passive provision for 5 car trains
(the platform extensions etc. are long enough for example).

Not sure about ELL but that is scheduled to have
16 tph on the core section when the new SLL opens in late 2012. I think
it will take a long time to exhaust the capacity of 16 tph on the ELL
although the southern branches may be fuller south of NXG.

Indeed. It's a lot of capacity, and my initial proposal is to extend
half the terminating trains from Dalston to Willesden, half the H&I
terminators to Harrow, and the rest to Watford. That gives your 15-
minute frequency from Watford to Harrow, and removes the need for the
Bakerloo to Harrow as you will have 8tph between there and Willesden
Junction.


The Bakerloo might struggle to reverse all its service at Queens Park
as only the central roads of the north shed can be used for reversals
(the two through tracks don't have access to the other platform).
Harrow does have the advantage that it has a central reversing siding,
which is not present at Stonebridge Park (where some of the Bakerloo
trains reverse at the moment).

However, this will become impossible thanks to the strange choice of
method chosen to link HS2 to HS1. They are proposing to tunnel a
single-track tunnel from Old Oak Common all the way to Primrose Hill,
then rise up and take over one of the tracks (widened to UIC gauge)
onward to St. Pancras. I suspect the widening required might require
the removal of the other track over the viaducts though. Why they
don't just continue the tunnel a few hundred metres more to St.
Pancras is beyond me. Sure it will save a tiny fraction of the cost,
but you're crippling the LO network's future prospects.

I think you need to define what you the LO network's future prospects
are before you can conclude that a HS2 link tunnel will cripple them.

I define the prospects as taking advantage of the Primrose Hill link,
which connects two parts of the LO network on either end. Severing
that link and removing the service to Euston (replacing north of
Queens Park with the Bakerloo) means closing Kilburn High Street and
South Hampstead. A simple, linear LO line from Watford to West Croydon
with short terminal branches to New Cross and Crystal Palace is very
simple for passengers to understand. Primrose Hill also offers a
opportunity to build an interchange with Chalk Farm, improving usage
on that section of line, and saving a good few pointless trips through
Euston for those wanting Camden.


But disrupting the journeys of those passengers who want the Euston
area rather than Camden; Kilburn High Road and South Hampstead are
quite busy with just the existing services from Euston.

As I say, I see the LO as SSL lines, just without the tunnelled core
sections, and I think they should be treated as such.

Imagine the carnage when that lot hit town.

I thought I was displaying my sense of humour. Ah well...
