5 car Overground trains to Watford Junction
 
I read in a magazine that Overground trains on the Euston-Watford service
won't be able to be extended to 5 cars until power supply upgrades have
taken place. I don't understand why power supply upgrades are is needed.
This route used to be served by 7 car Bakerloo Line trains.

Guessing but perhaps "used to" are the operative words in that sentence,
i.e. the power supply kit / arrangements on the line have changed since
1982.

And maybe 5-car 378s, with modern traction equipment, need more power than
old tube trains (1972 stock, presumably)?

1938 stock actually. I guessed it's the same as the Southern. Massive power
supply upgrades were needed for the switch from camshaft-controlled stock to
power electronics.

You have to wonder why it was necessary if the claims about electronic control
being more efficient are true. Surely that couldn't have been marketing fluff
could it?

I now recall reading about it at the time. The characteristics are different
and break old supplies. The efficiency mainly comes from regeneration of
course.

I think my question was really because I didn't realise the new 5th cars

The line is basically full of old restrictive "make do and mend"
signalling and traction current. It's no shock that putting bigger
trains on to the route might be enough to tip things over. The
traction supply has been strengthened or replaced on all the LU routes
that are getting major upgrades and new rolling stock.

I think the TfL game plan is simply to put new 4 car trains on the
route. These have been added to the GOBLIN / West Anglia order. The 5
car trains displaced will be diverted to strengthen other Overground
routes. Clearly those trains won't turn up until 2017.

As reported elsewhere there are also issues with the traction current
supply nearer to Watford where the Met extension would run over NR
tracks. Costs have gone up because of the need to do something to the
traction current supply. There is little detail in public at the
moment but I'd guess the parsimony and cut backs of the 80s are now
having an impact at far, far greater cost.


So true! I've been watching the Borders Railway videos and can't stop
thinking how much they would have saved by not closing the line in the first
place.

I think the new traction packages draw a much heavier current during the
initial acceleration phase. It was one of the urgent projects the SRA had
to deal with when the new 'lardbutt' Siemens Desiro trains were introduced
by SWT. I seem to remember Roger Ford writing about in MR at the time. The
old traction supplies might also need beefing up to cope with regeneration
as well.

Forgive me, please, if I asked this question earlier, but what's the
deal at this point with re-extending the Bakerloo Line out to Watford
Junction? Or is that dead with the emphasis now on extending further
south from Elephant & Castle?

IIRC, one of the reasons that LUL service has not developed much south
of the river is because that part of town is largely on sand.

That's been dead for years, long before the southern extension of the
Bakerloo became an active proposal. And there's no chance if it now, with
the Met also going to Watford Junction.

IIRC, one of the reasons that LUL service has not developed much south of
the river is because that part of town is largely on sand.


That was part of the original reason a century or more ago, but it's not
much of an issue with modern tunnelling methods. Ditto with building larger
diameter tunnels, so we won't see any all-new small gauge tube lines.

Seems odd given its the cheapest line "extension" they could do. Just plonk
the 4th rail back on its insulators and bobs your uncle. The power supply
system is already in place.

There's not enough traffic to warrant it, and there won't be enough
platforms for Bakerloo trains to terminate and reverse at Watford Junction.

I always thought modern traction actually used less current during initial acceleration but continued to draw high currents giving them better acceleration at higher speeds.

378s are quite slow to accelerate on the Watford DC lines so I suspect the current draw is too mahoosive

They're just slow full stop. They're completely the wrong sort of train for a
metro service. But no doubt the slight design mod of an existing outer suburban
train was the cheaper option.

I happened to have my GPS with me on an LO trip to Watford yesterday, and
found that the peak speed was about 45mph. Considering how closely spaced
the stations are, that's probably not bad, and hardly slower than an S
stock train would do it. S stock trains reach their higher speeds of about
60mph only on the longer non-stop sections, such as Finchley Rd to Wembley
Park.

But LO trains have very relaxed schedules, and often wait longer than
necessary at stops, thus helping achieve their very good punctuality. LU
trains, with their lack of published schedules, don't have to do this.

That's why I used the word "public". But the Amersham and Chesham branches
are infrequent enough that the scheduled times do matter; I doubt that many
people worry about the schedules on the Uxbridge and Watford branches,
except in the very early mornings and late at night.

It's possibly changed, but when I last checked the speed limit on that
line was 45 mph from South Hampstead to Bushey (with a few short bits
with a lower limit) and 35 from there to Watford. Trains without
tripcocks were restricted to 25 south of Harrow & Wealdstone. Goods
trains were restricted to 15 and 40 respectively.

Their top speed isn't the issue - its 75mph according to wonkypedia. Its their
acceleration. On the ELL they're so slow off the mark they barely get up to any
decent speed before they have to slow down again for the next stop. I can only
assume the stations on the watford branch are further apart. Either that or we
enter conspiracy theory land and assume there's a deliberate policy on the ELL
to provide a slow service.

Could there be something about not overloading the power systems? I
believe the acceleration on the S-stock is artificially impeded for
that kind of reason (also to stop them catching up any remaining
classic stock) - they *could* take off like European U-/S-Bahn stock
often does, or like the 350s do here.

I think that when the A stock were still in service, that S stock
performance was restricted, but hopefully the S8s are no longer
limited. But it's very likely that they do draw more power than an
equivalent length 378 would, which might be a problem on the Watford
Junction DC line if they weren't planning to upgrade the power supply.

I'd imagine the power systems on the northern part of the ELL are all brand
new so I wouldn't have thought so. But who knows these days, cost cutting seems
to be the #1 priority.

And Circle line trains frequently do, as announced by the driver, at Aldgate.


Yes, the Circle line is quite infrequent, so trains do need to be
regulated.

I'd imagine the power systems on the northern part of the ELL are all brand

to be the #1 priority.

There wouldn't be an Overground service at all if that was the case.

Would you say Shoreditch High St was done "on the cheap"? But if you
really expected the LO to be engineered to your exacting standards, it
simply wouldn't have been built. We'd still have the old ELR with its
sparse service, which you'd never have used, and therefore never have
complained about.

I seem to recall that you've also criticised the original DLR for bing
built on the cheap, which it certainly was. But if you think anyone could
have found the budget back then to build something resembling today's much
extended DLR, you obviously would like to pay a lot more in taxes.

The stations on the ELL are very close together.


No closer than on many tube lines including the met but tube trains get up to
speed much quicker because they have appropriate gearing.

If they'd simply built the section north from whitechapel and instead of the
idiotic decision to stop at H&I instead of finsbury which would have
provided an interchange with the ECML it would have been a much more useful
line and cheaper. There was no need to co-opt pre existing sound london lines
since they were already perfectly well served.

It's been said for well over a decade now that lengthening Rotherhithe and Wapping
would either be too difficult or impossible. Selective door opening is common on
bits of the tube network which are far newer.

You repeatedly say this, but repeating it doesn't mean it makes any more sense.
None of the southern branches are quiet, suggesting they weren't already perfectly
served. Admittedly, without those passengers it wouldn't be as crowded on the
northern section, but without them you wouldn't have the "poor" 16 train an
hour frequency.

Or an extended ELL at all. I can't imagine it having been funded just to extend
New Cross to Highbury & Islington. Would it even exist at all by now?

I was curious to find out how slow it is between H+I and Canada Water, and how
this compared to the Victoria + Jubilee line. It's timetabled 20 minutes direct by
Overground, and 9+11 minutes on the Underground. The same! Only wait, there's
the time involved in changing at Green Park, which TFL's journey planner seems to
put at around 4 minutes. I know such things can exaggerate changing time, but
there seems to be no way to do this journey quicker by tube.

The Underground route is about 2 miles longer and has one more stop so yes,
the average speed is higher. The average speed of the Underground trip including
stops is about 23mph, the Overground about 17mph. Neither are going to set the
world on fire. And on average, the Overground's stops *are* closer together, with
10 of them in less than 6 miles.

I was actually surprised the Underground wasn't faster by a bigger margin, especially
as both lines are ATO. I often wonder if people assume that deep level tubes are
travelling faster than they are due to their size, the small tunnels and the "zoom"
effect the cabling on the walls has.

Well it makes more sense than thousands of people spilling out at finsbury,
shuffling onto the victoria line - which is already seriously overcrowded there
in the rush hour - for one stop then getting off at highbury when there is an
underused freight line - albeit single track - onto the NLL that could have
been used for passenger trains.

No, it would be much higher.

Well it has provided a sort of tube service to parts of london that were
reliant on a bus previously. What has it added to south london? The ability to
get to canada water without changing at london bridge. Big deal.

Well it is quicker by tube. Incidenatly last night I decided against my better
judgement to give the overground another go. I spent FIFTEEN minutes waiting
at Dalston for a highbury train because one train just sailed on through without
stopping.

I was actually surprised the Underground wasn't faster by a bigger margin,


It is faster by a big margin. I suggest you try it instead of relying on the
fiction that is TfLs timetables.

Wasn't Rotherhith proposed for closing when the JLE opened with Canada Water
taking the strain? And again more recently with the ELL conversion weren't
they talking about closing both and screwing Wapping?

Doesn't matter - they did it. Given how long the ELL was closed for to convert
it they had plenty of time and compared to the works that were required to
raise the line out of the tunnel at shorditch I suspect it would have been
a relatively minor addition to lengthen platforms.

The critical timing was how long they could close the dock for, as it's
on the route between the river and ExCel, which has an annual boat show.
There was a documentary about the project in the Autumn, and they
finished it by the skin of their teeth.

highbury when there is an underused freight line - albeit single track
- onto the NLL that could have been used for passenger trains.


It was singled to get it electrified through the tunnel which would
otherwise have been problematic. It's not really an answer here because it
would mean a flat crossing of the North London line.

So? Its not the M25. I've waited at H&I and not seen a train go past on the

ITYF that capacity is already constrained on the NLL, mainly unsatisfied
freight paths.
