Was just thinking about the ELL (yes I truly have no life) and got to
thinking:

When the East London line is closed this December, will the A stock be
used to reinforce any services on the Metropolitan line, or to
implement the change of the terminus from Aldgate to Barking before
the introduction of S stock? Or will they just be stored away and used
as spare sets in case of breakdown?

On the subject of the ELL, how is it going to be electrified?
(Yes, I know it has electrification at the moment and steam trains no
longer run under the river).
Perhaps a stupid question, but on any part of the proposed orbital
railway (ie. ELL, NLL etc) are there any overhead lines?
I guess not.

The ELL will be DC third rail - and I shall be very surprised if in due
course it isn't run by Southern, as contractors to TfL as the services will
have to be timetabled into the existing paths, indeed the extension of the
railway to Crystal Palace and Croydon will subsume certain existing
services.

The NLL and WLL have a mixture of DC third rail and 25kV ohle at the moment,
and the stock is currently dual voltage just like Thameslink, and will
remain so, although there are various proposals for extending the 25kV
setions of the NLL. I'm sure there are details of the stock requirements on
TfL's website somewhere...

Current bidders for London Overground (= NLL, ELLx, WLL, GOBLIN) are
MTR/Laing (Chiltern) and GoVia (Southern). AIUI the Southern franchise
deal allows for transferring certain services to ELLx when it opens,
so this side of things won't be a problem whoever wins.

Network Rail is supposed to be able to resolve timetable conflicts
between different operators, and doesn't do a terrible job: for
example, although the South Central and South Eastern franchises have
been under the same control for much of privatisation (Connex and now
GoVia), the period when GoVia and SRA were running South Central and
South Eastern respectively was not a disaster.

Also, the LO franchise is rather different from the South Central
franchise, in that it's far more tightly specced and responsible to
TfL - much of the strategic/planning work that GoVia does for Southern
will be done by TfL for LO.

So overall, I don't think GoVia has the kind of advantage in bidding
that you're suggesting - although they might win by default if it
transpires that Laing's new owners don't have the same interest in
rail as the previous management.

What does seem useful is that whatever (small number of?) Southern
paths/services are effectively transferred to ELL, the displaced rolling
stock will remain available for strengthening other services...

Just to be clear on this, the MTR/Laing joint venture doesn't run the
Chiltern Railways franchise - that's owned directly by Laing. MTR is
Hong Kong's Mass Transit Railway company, who don't currently operate
any franchises in the UK rail market. I have read a number of comments
from people who think they would make an interesting choice - even if
only as one half of a joint venture - and might shake things up
somewhat.

I was interested to read what you said re the Southern franchise -
that the SRA / DfT had the foresight to ensure the agreement with
Govia was flexible enough to accommodate the forthcoming ELLX. It's a
pretty obvious move when one thinks about it - it's just that I
hadn't.

Though the operations of the South Central (i.e. Southern) and South
Eastern franchises are surprisingly discrete - they quite literally
don't cross paths that often (at least not on the level).

First Capital Connect's Thameslink route however crosses both their
paths, especially on the run in to London Bridge, which is what the
Thameslink 4000 project is aimed at dealing with.


Also, the LO franchise is rather different from the South Central
franchise, in that it's far more tightly specced and responsible to
TfL - much of the strategic/planning work that GoVia does for Southern
will be done by TfL for LO.


TfL refer to the London Overground operator arrangements as a
concession, as opposed to a franchise, so the winning operator will be
the concessionaire.

I'm no expert on Merseyrail, but it is already run on this concession
basis - the Merseyside lines are run by a Serco/NetRail joint venture
for Merseytravel (the Merseyside Public Transport Executive). The
London Overground and Merseyrail concession arrangements look similar,
at least superficially - I've no idea comparable the two are when
looked at comprehensively though.


So overall, I don't think GoVia has the kind of advantage in bidding
that you're suggesting - although they might win by default if it
transpires that Laing's new owners don't have the same interest in

I suspect that you may be right. It may be of interest that the initial
thoughts of the powers that be were that the ELL would have control and
priority of all the main line sections it was extended over! I had to
prepare a few high level tender calculations based on that design although I
had to add very strong riders about the inadvisability of even attempting it
and the unlikeliness of it going ahead - it didn't!

I guess not.

Currently, NLL is electrified 2 tracks OHLE from Acton to Camden Road,
then one track OHLE and 2 tracks DC to Dalston, then 2 tracks combined
OHLE and DC to Lea Junction, then DC to Stratford:

http://www.networkrail.co.uk/documen...NLL.pdf#page=6

SLL is third-rail-only, and the WLL is third-rail south of North Pole
and AC-electrified north of it. GOBLIN is unelectrified except for a
few bits round Barking and (IIRC) Walthamstow.

In the future, the Cross-London RUS suggests converting the NLL east
of Camden Road to fully AC-electrified and leaving the WLL as-is:

http://www.networkrail.co.uk/browse%...us.pdf#page=36

The SLL will remain third-rail-only until the ex-Southern Region
converts to overhead AC, which will be never. If the GOBLIN is
electrified, it will be overhead AC.

This leaves the ELL itself. I'm fairly sure this is third-rail from
New Cross / New Cross Gate to Dalston: although I haven't read
anything explicitly stating that this is the case, none of the TfL
publicity pics have OHLE masts in them and I'd be sceptical that the
tunnels have the necessary clearance.

Beyond Dalston, there's an implication that either the ELL
Electrostars (which will continue initially to Highbury, maybe later
further on) may need to be dual-voltage with a switch-over at Dalston,
that the conversion of the NLL to OHLE east of Camden will not take
place, or that a dual-voltage section of track will be required
between Highbury and Dalston.

Not sure which is happening here. One suggestion is to re-instate four-
tracking between Camden and Dalston, which would be sensible, and then
to dedicate one pair of tracks between Highbury and Dalston
exclusively to the ELL with the other shared between NLL and freight,
which would be barking mad, given that ELL and NLL trains will run at
the same speed in the same direction making the same stops and freight
won't. But if this did happen then you'd expect the NLL tracks to be
OHLE and the ELL tracks to be DC.

That's what I thought. Brunel probably didn't leave enough room for
future overhead electrification.
